    Abstract [en]

     

    The war poetry of Erik Axel Karlfeldt (1864-1931) is a neglected part of the poet's work. The aim of this article is to discuss three poems from Flora och Bellona (1918): "Det röda korset" ("The Red Cross"), "Svart Jul" ("Black Christmas") and "En pesthymn" ("A Hymn of Pestilence"). Attention is paid to the ideological level of the poems, but also to their poetic structure. The poems are related to Peter Hallberg's discussion of Karlfeldt's archaistic imagery, to Esaias Tegnér's "Svea", but also to the contemporary political poetry of outspoken nationalists and socialists. Compared to the explicit political poetry, Karlfeldt's poetry is complex, often ambivalent in its criticism of both belligerents and alternately displaying despair and optimism. "En pesthymn" can be seen as a turning point, mirroring the outbreak in 1918 of the Finnish Civil War. In this poem, the ambivalent moral judgements of the poet's preceding war poetry are replaced by unequivocal political support for the "Whites".

    Hur unga utlandsfödda invandrare blir bemötta i det svenska samhället.: En kvalitativ och kvantitativ studie om diskriminering och rasism2010Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning: Ungdomar med utländsk bakgrund har enligt tidigare studier sämre förutsättning i skolan, arbeten och inom rättsväsendet, på grund av diskriminering. Syftet med denna uppsats har varit att ta reda på hur unga utlandsfödda ungdomar blir bemötta i det svenska samhället, samt att se om det finns vissa specifika mönster till varför det uppstår diskriminering i bland annat skolan. Till vår undersökning använde vi oss av teorier om - diskriminering och rasism, som används i analysen av det empiriska materialet. Vår utgångspunkt i uppsatsen har varit att ta reda på varför diskriminering och rasism sker i samhället. Vi hade ett antal frågeställningar som kan ses nedan, som besvarats i arbetet.

    • Hur blir invandrarungdomar bemötta i det svenska samhället utifrån deras etniska bakgrund?
    • Spelar ungdomarnas genus någon roll i hur de blir bemötta i det offentliga samhället?
    • Finns det skillnader mellan ungdomar med olika bakgrund beroende på deras vilken världsdel de kommer ifrån?
    • Påverkar ungdomarnas socioekonomiska och kulturella bakgrund, hur de blir bemötta i det svenska samhället?

           För att besvara dessa frågeställningar, delade vi ut enkäter till 42 ungdomar i en mellan stor stad i åldrarna 16 – 24 år i olika skolor. När resultatet av enkäterna var sammanställda valde vi att ha en fokusgrupp med fyra deltagande som hade deltagit i enkätundersökningen. Syftet med att ha en fokusgrupp var att få en fördjupad kunskap om vissa svar kring rasism och diskriminering. Vårt resultat i studien visade att ungdomar med utländsk bakgrund, blir diskriminerade ute i samhället utav skolan, polisen, socialtjänsten, i affärer, på arbetsplatser samt på andra platser i samhället som till exempel på bussen. Dessa slutsatser stärktes och jämfördes sedan med tidigare forskning i en analysdel, samt en avslutad diskussion.

    Lokal och regional klimatsamverkan - en räddare inöden?: En fallstudie av hur sektorsöverskridande klimatsamverkansinitiativ på lokal ochregional nivå arbetar för att reducera geografiskt kopplade växthusgasutsläpp2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To collaborate cross-sectoral on a local or regional level has been identified as a possible solution toachieve a more effective way of reaching set climate targets. Therefore it´s of interest to conductfurther study in how these initiatives collaborate in their aim of reaching climate related targets.This thesis is a case study consisting that examine how cross-sectoral climate collaborations on alocal or regional level collaborate to reduce the emissions of territorial greenhouse gases.Furthermore, the study investigates what challenges and advantages the objects of study areexperiencing and also to identify what factors the initiatives are experience that creates a long-terminitiative and an attractive collaborate-organisation. The objects of study are Climate Council inJönköpings region, Climate2030 in Västra Götalands region and Uppsala Climate Protocoll, GothenburgClimate Partnership, Lund Climate Alliance and The Linköping Initiative.The collection of the empirically data was gathered via semi-structured interviews with either theprocess manager, administrator or executive manager in each initiative.The study shows that the public sector has the major responsibility in initiating, administrate andfinancing the initiatives. The study also shows that there is no established templated or collaboratemethodin local or regional climate-collaboration, which results in both similarities and differences inthe initiatives structural design.The study has found that focus-groups, the use of climate related challenges, climate agreementand to work in specific projects are all commonly used work procedures, but with differences betweeninitiatives.Furthermore, results show that participation, anchoring and experience- and knowledge-exchangeare key factors that the initiatives are experiencing in how to create an attractive and long-termcollaborate initiative. Moreover, it emerges that the initiatives are experiencing both benefits with aclimate collaborating because it helps members of the collaboration to go from words into action, andpartly challenges regarding how to prove its actual effect in reducing territorial greenhouse gasemissions.Finally, the study notes that the subject, local and regional climate-collaboration is relativelyunexplored and that it needs further research for example in what function a climate collaboration hasand what effect the initiatives creates.

    Technology-enhanced Speech and Language Relearning for Stroke Patients- Understanding the users and their needs for technology acceptance2021Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Stroke is a rapidly increasing disease worldwide, and speech and language impairments are common in stroke patients. A patient’s ability to speak, listen, read and write is reduced after stroke which affects the patient's independently living and quality of life. After an initial evaluation at the hospital, the stroke survivors are referred to the stroke rehabilitation centre where the speech therapists assist them in their challenging and long journey towards speech and language relearning. To enhance the patient's quality of life and to facilitate the speech therapists, technology-enhanced systems can play an important role. However, the currently used software applications such as online speech and language relearning applications are not specifically designed after the user’s need, and the user’s participation and empowerment are compromised. Medical caregivers and stroke patients are the main stakeholders and potential users of these software applications. Therefore, this study is aimed to understand the medical caregivers and the stroke patients’ needs for technology-enhanced speech and language relearning from medical caregivers’ viewpoint. 

    Design science research strategy was adopted to create, implement and evaluate the artefact. Some important stakeholders such as speech therapists, a stroke specialist doctor, information and technology professionals and one stroke survivor participated in this study. Following the speech therapist’s expert opinion, an application for speech and language assessment was developed as an artefact. The application was then evaluated for technology acceptance with the speech therapists. The Unified Theory of Acceptance and Use of Technology (UTAUT) was used as the theoretical foundation for making the interview questions and data analysis. 

    The user's requirements for software application differ from one patient to another depending upon the patient's overall health after stroke, their age, social life, the level of speech and language loss, and previous experience with technology use. Stroke is common in adults and adults like to participate in designing their relearning process; therefore, adults should be involved in deciding the learning objectives, and adult learning principles are helpful to understate their needs for speech and language relearning. Due to impaired physical and cognitive conditions, the patients need a bigger interface with larger fonts and pictures and more constructive colours than usual. Tablets with touch pens are preferred hardware. The speech therapist should have the possibility to change the exercises runtime according to the patient's abilities and stamina to do the exercises. 

    The technology acceptance evaluation showed that the developed application was easy to use and efficient for speech therapists. The study participants also highlighted some critical issues for better usability and technology acceptance. The application should be synchronized with speech therapists’ existing workflow and routines, and it should directly be connected to the hospital records system so that the patients’ data can easily be transferred to their journals. 

    The role of facilitating conditions such as proper education and training about the system, and personalised support is also important in technology acceptance. The user’s trust in the system’s security and privacy and their personal integrity were also highlighted as main determinants for technology adoption and use. To achieve better coherence between the users and technology, all the tasks/exercises and sub-tasks in the application should be designed in close collaboration with speech therapists and stroke patients. Due to the Covid-19 pandemic, only one stroke survivor was interviewed in this study. However, the patients’ perspective is of utmost importance, and in future research, they will be involved in the design and development of such technology-enhanced systems.

    Technology Acceptance of an Online Speech and Language Assessment Application for Stroke Patients - the Medical Caregivers' Viewpoints2021Conference paper (Refereed)
    Abstract [en]

    Stroke is a globally increasing disease and speech and language deficiencies are common in stroke survivors. To facilitate medical caregivers in their professional work and to improve patients’ quality of life, technology can play an important role.  However, the use and acceptance of technology are uncertain and more research is needed in this direction. This study evaluates the technology acceptance and adoption of an online speech and language assessment application. The evaluation focused Design Science Research strategy was adopted for that purpose. Two physiotherapists, one occupational therapist and three speech therapists participated in the study. The Unified Theory of Acceptance and Use of Technology (UTAUT) was used as the theoretical base for interview questions formation and data analysis. The study findings show that the suggested application is useful and easy to use; however, it should be more synchronised with speech therapists’ daily work routines. The speech therapists stressed that functionalities of the application should be designed in close collaboration with them, and it should be compatible with the already existing systems and services in place.  Due to the impairments after stroke, the patients have some specific preferences for software and hardware such as a tablet with touch pen is the preferred hardware. Additionally, the interface should have bigger text fonts and pictures, and highly contrastive colours in the graphics should be used for patients’ convenience. The user’s privacy and security, patient’s current health, and their previous knowledge and experience about technology were also found important determinants for intention to use the given technology.

    Technology-enhanced speech and language relearning for stroke patients: defining requirements for a software application development2020Conference paper (Refereed)
    Abstract [en]

    Speech and language relearning are challenging for stroke survivors as well as for medical caregiv-ers. After a stroke, a patient’s ability to read, write, speak, and listen is decreased to different degrees, which results in a compromised independent life and a decreased quality of life for the patient. Tech-nology enhances systems can play a vital role in this context. However, the available software are not specifically built for after the stroke patient’s needs. This paper is therefore aimed to gather require-ments for designing a tailor-made speech relearning software application for stroke survivors. A de-sign science approach was adopted, where different stakeholders such as medical caregivers and in-formation technology consultants were involved in the process. The well-informed and experienced participants in their fields highlighted some important requirements such as different types of inter-face for a patient than speech therapist with extra management functionality for speech therapists so that they can adjust the relearning exercises according to the patient’s needs. Software requirements vary from patient to patient where the intensity of speech and language impairments, general medical condition of the patient, age, prior experience, and knowledge about the information of the patient and social setup of the patient plays an important role. Since stroke is most common in adults and adults learn differently than children, adult learning theory might help understand the patients' needs. There-fore, adult learning principles were involved in the requirement analysis process. The established re-quirements will be used for the development of speech and language relearning software.

    The Technology-Enhanced Requirements for the Three-Fold Stroke Rehabilitation to Support Independent Living2020In: Information and Communication Technologies for Ageing Well and e-Health, Switzerland: Springer Nature, 2020Chapter in book (Refereed)
    Abstract [en]

    Stroke is a common and severe disease that can be found in all regions across the globe, and not onlyamong older adults. Result of a stroke can be death, or a variety of disabilities caused by impairments indifferent brain functions. This chapter discusses technology enhanced stroke rehabilitation from a threefoldview of cognitive, motoric and speech rehabilitation. The important research question was: Whatwould be the requirements for technology-enhanced stroke rehabilitation in the areas of cognitive, motoricand speech rehabilitation? The study was carried out with a requirement-focused Design Science approachcollecting data with semi-structured interviews. Informants were selected in a purposive sampling choosingprofessionals with valuable knowledge and skills in stroke rehabilitation. The findings in this study havegenerated useful general requirements for a future implementation and testing of technology enhancedstroke rehabilitation. Within each of the three rehabilitation categories cognitive, motoric and speech, thereseems to be potential for successful use of technology enhanced services. This development ofrehabilitation services must follow the fundamental principle for all forms of stroke rehabilitation: eachpatient needs a personalised treatment. However, in all three rehabilitation categories, there is a need todefine more specific requirements based on feedback from stroke patients testing the rehabilitationservices.

    Critical Factors for Human Computer Interaction of eHealth for Older Adult2019In: Proceedings of the 2019 the 5th International Conference on e-Society, e-Learning and e-Technologies, Vienna: Association for Computing Machinery (ACM), 2019, Vol. 5, p. 58-62Conference paper (Refereed)
    Abstract [en]

    The percentage of older adults increases globally with an increased need for medical care. To support the idea of successful active aging, e-health seems to be an interesting concept. This study was conducted as a systematic literature study, with the aim to identify and discuss determinant factors in the Human computer interaction of eHealth for older adults. The important main research question to answer was: What are the critical challenges to address for an improved human computer interaction in technology enhanced health care systems for older adults? Findings show that there are several critical factors to consider, with trust, personal integrity, technological acceptance, e-health literacy and accessibility of ICT as the most determinant. If the found challenges are addressed, it might be possible to achieve the identified aim of independent living. The recommendation is a human computer interaction that is elderly centred, and involves the elderly users in the design process. However, no ICT enhanced system will be user-friendly enough to take away the need for social and technological support.

    Human-Computer Interaction for Older Adults: a Literature Review on Technology Acceptance of eHealth Systems2022In: Journal of Engineering Research and Sciences (JENRS), ISSN 2831-4085, Vol. 1, no 4, p. 119-126Article in journal (Refereed)
    Abstract [en]

    The population of older adults globally increased during the last couple of decades. Due to these demographic changes, the need for medical care has also significantly increased. Despite the age-related disabilities and chronic diseases, most older adults prefer independent living in their home environment. Technology-enhanced systems and eHealth applications seem to provide some promising solutions for older adults’ well-being and independent living. However, the adoption and acceptance of these applications for older adults are unclear and further research is needed in this area. This study was carried out as a literature review, to meet the aim of identifying and discussing important factors in the Human-computer interaction of eHealth for older adults. The overall research question for this study was: What are the critical factors to consider for an improved human-computer interaction in technology-enhanced health care systems for older adults? Findings indicate some important factors to address: personal integrity, trust, technology acceptance, accessibility of ICT and eHealth literacy. If the presented factors are considered and addressed, it would be easier to achieve the desired aim of independent living. The authors recommend a human-computer interaction that is older adults centred, with the involvement of older adults users in the design process. Proper education and training on the use of eHealth services are also of great importance. Finally, the technology-enhanced system should also provide good social and technological support to the users.

    On the Importance of Tailor-made Speech Relearning Software for Stroke Rehabilitation2020In: Proceedings of the 6th International Conference on Information and Communication Technologies for Ageing Well and e-Health - Volume 1: ICT4AWE / [ed] Leszek Maciaszek,, SciTePress, 2020, Vol. 1, p. 176-179Conference paper (Refereed)
    Abstract [en]

    Post stroke rehabilitation is a global issue with increasing challenges today when the percentage of older adults is increasing. There is a need for new solutions to better assist stroke survivors' normally long way back to a good and independent life. The various post stroke impairments can be divided into the categories of cognitive, motoric and speech impairment, and the three also have their interrelations. This position paper has a focus on rehabilitation of stroke survivors' speech impairments, and the use of technology-enhanced systems to assist the speech relearning. The current reuse of language learning software for primary school students is doubtful, and should better be replaced by tailor-made and adaptable tools that fit the target group. Finally, the recommendation is a long-term strategy where some initial costs should fund the design, development and evaluation of new digital tools for speech relearning. This should be conducted in a collaboration between researchers, speech therapists, stroke patients. The approach should be iterative and user-centred, with both speech therapists and stroke patients as the end-users.

    Factors Influencing Acceptance of Technology-enhanced Speech and Language Relearning for Stroke Survivors – A Systematic Review2021In: 7th International Conference on e-Society, e-Learning and e-Technologies Portsmouth, United Kingdom, June 10-12, 2021, Association for Computing Machinery (ACM), 2021, p. 86-91Conference paper (Refereed)
    Abstract [en]

    Speech and language loss is the most common disease for stroke survivors. The process of relearning communication skills is difficult and a time taking process. Technology-enhanced systems (TES) can be useful in speech and language relearning, however, the acceptance and usability of TES for stroke patients have been a matter of concern and more research is needed in this area. This study is therefore aimed to explore the factors that might influence the acceptance of technology-enhanced speech and language relearning after stroke. A systematic literature review was conducted to determine the technology acceptance factors. To ensure the state of the art in the given field, 97 articles written from 2016 to April 2021 were retrieved with a search string aligned to the research question. After applying the exclusion criteria and quality assurance, 13 articles were selected for inclusion. An overview of selected articles, their chosen methodology, and main findings from the articles was presented in a pre-defined table. The results show that patients’ physical and cognitive condition, the intensity of relearning exercises, native language, the involvement of friends and family, technical assistance and training, selection of hardware and usability of the graphical interface are important factors for acceptance of TES. Stroke patients tend to use TES. Independent living, treatment in the home environment, and improved quality of life are the major motivations for use of TES. However, TES should be tailor-made and a user-centre approach should be adopted. Finally, proper education and training are essential not only for the patients but for the speech therapists and patients’ relatives and friends as well.

    Testbed requirements for technology enhanced stroke rehabilitation to support independent living2019Conference paper (Refereed)
    Abstract [en]

    An identified global phenomenon is that, as the percentage of older adults increases, new challenges arise for medical care and rehabilitation. Several research studies have presented e-health as a promising concept to support the idea of independent living among patients with chronic diseases. The Mid Sweden region has a relatively old population and is a region where people live with long distances to the nearest hospital or health care centres. This study had a focus on defining testbed requirements for a technology enhanced stroke rehabilitation adapted to the specific region. The focal research question to answer in this study was: What are the requirements and their associated benefits and barriers of using technology-enhanced systems instead of traditional techniques for stroke rehabilitation in the Mid Sweden region? With Design Science as the overall research strategy, data was collected by semi-structured interviews with key stakeholders in the field of stroke rehabilitation. A deductive thematic analysis was conducted where important themes were grouped into the four main requirement categories of: Technical, Human-computer-interaction, Clinic and Sustainability. Beside the more specific requirements, an interesting finding was the division of stroke rehabilitation into the categories motoric, cognitive and speech rehabilitation; also, how technology enhanced solutions might be used in these categories. Each category has a potential for a successful use of technology enhanced services, but as the standard procedure in traditional stroke rehabilitation each patient needs a personalised treatment.

    Speech and Language Relearning for Stroke Patients- Understanding  User  Needs for Technology Enhancement2021Conference paper (Refereed)
    Abstract [en]

    Speech and language relearning are challenging for stroke survivors, as well as medical caregivers. After a stroke, patient’s ability to read, write, speak, and listen is decreased to different degrees, which results in a compromised independent life and a decreased quality of life for the patients. Technology-Enhanced Systems (TES) can play a vital role in this context. However, the available software are not explicitly built for recovering stroke patients’ needs but often for children’s learning needs. This paper is, therefore, aimed at gathering requirements to support the design of speech and language relearning software applications for stroke survivors. A design science approach was adopted, where different stakeholders such as medical caregivers and information technology consultants were involved in the process. Deductive thematic analysis was conducted to analyze the main findings according to adult learning theory. The software requirements vary from patient to patient where the intensity of speech and language impairments, general medical condition, age, prior experience, and knowledge about the previous health record, and social setup of the patient are playing an important role. The speech therapists should have management functionality in the software to adjust the relearning exercises according to the patient's needs.  Since, stroke is most common in adults who learn differently than children, andragogy principles were useful in recognizing patients' health conditions. Adults are interested to be involved in the development of their relearning process. Software for speech and language assessment will be helpful to establish relearning objectives for patients.

    Palliativ vård av äldre i hemmet: En litteraturöversikt ur närståendes perspektiv2023Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Att vara närstående till en döende person som får palliativ vård i hemmet innebär stora påfrestningar som påverkar dem psykiskt och somatiskt. Sjuksköterskor som tar hand om palliativa patienter utgår från de fyra hörnstenarna; symtomkontroll, samarbete, kommunikation och relation, samt stöd till närstående. Närstående till äldre personer som får palliativ vård i hemmet blir ofta delaktiga i omvårdnaden, ibland ofrivilligt, därför är det viktigt att belysa deras upplevelse för att kunna identifiera vilka behov eller resurser som finns i takt med ökat palliativ vårdbehov i hemmet.

    Syfte: Syftet var att belysa upplevelser av att vara närstående till en äldre person som får palliativ vård i hemmet. Metod: Metoden var en litteraturöversikt av vetenskapliga originalartiklar. Sökningar gjordes i två databaser, PubMed och CINAHL, och 14 kvalitativa artiklar användes till resultatet efter urval- och granskningsprocessen.

    Resultat: Många närstående inte ville lämna den äldre personen ensam och åsidosatte sina egna behov. De upplevde en plikt mot den äldre personen att delta i den palliativa omvårdnaden och saknade tillräcklig kunskap. Brist på stöd och information gav negativa upplevelser. Att bli sedd av vårdpersonal var betydelsefullt.

    Diskussion: Att leva med en döende person påverkade närståendes psykiska hälsa genom upplevelser av bland annat oro, rädsla och ångest. Sjuksköterskan kan ge stöd genom information och utbildning.

    Slutsats: Genom att se närstående som en person med egna behov av stöd och hjälp samt arbeta utifrån ett personcentrerat förhållningssätt kan sjuksköterskan minska ansvarsbördan och främja hälsan och välbefinnande hos närstående.

    Familjebehandlingsarbete med dysfunktionella familjer och med barnet i fokus2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens syfte var att undersöka och förstå vad en dysfunktionell familj är enligt familjebehandlare samt hur familjebehandlingsarbete fungerar med dysfunktionella familjer och med barnet i fokus. Studien är kvalitativ och den datainsamlingsmetod som har använts är semistrukturerade intervjuer. I studien intervjuades fem familjebehandlare. Det empiriska materialet har analyserats genom en innehållsanalys. Studiens resultat är uppdelad i tre olika teman, vilka är definition av en dysfunktionell familj, arbetsmetoder samt barns bästa. I resultatet framkom det att alla familjebehandlarna är överens om att alla familjer som de kommer i kontakt med i sitt dagliga arbete är dysfunktionella familjer. Kortfattat beskriver behandlarna att dysfunktionella familjer är familjer där något inte fungerar som det ska samt där barnet i familjen inte får sina behov tillgodosedda. Vidare i resultatet framkom det att olika typer av samtal med familjer är en mycket central arbetsmetod inom familjebehandling. I resultatet framkom det även att familjebehandlarna inte kommer i kontakt med barnet lika mycket som med föräldrarna i sitt arbete. Familjebehandlarna försöker dock vara medvetna om att det är för barnets skull som de utför sitt arbete samt att de hela tiden arbetar efter barnets behov och inte efter föräldrarnas behov.

    Machine Learning Meets Communication Networks: Current Trends and Future Challenges2020In: IEEE Access, E-ISSN 2169-3536, Vol. 8, p. 223418-223460Article in journal (Refereed)
    Abstract [en]

    The growing network density and unprecedented increase in network traffic, caused by the massively expanding number of connected devices and online services, require intelligent network operations. Machine Learning (ML) has been applied in this regard in different types of networks and networking technologies to meet the requirements of future communicating devices and services. In this article, we provide a detailed account of current research on the application of ML in communication networks and shed light on future research challenges. Research on the application of ML in communication networks is described in: i) the three layers, i.e., physical, access, and network layers; and ii) novel computing and networking concepts such as Multi-access Edge Computing (MEC), Software Defined Networking (SDN), Network Functions Virtualization (NFV), and a brief overview of ML-based network security. Important future research challenges are identified and presented to help stir further research in key areas in this direction.

    Development and Characterization of Large Area Pressure Sensors and Sitting Posture Monitoring Systems2021Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    With the emergence of the Internet and rapid development of science and technology over the past few decades, many individuals worldwide now rely on the Internet to conduct daily activities ranging from education, business and creativity to communication and shopping. As we tend to spend more and more time on the Internet and engage less in physical activities, this persistent behaviour could result in some health-related issues within a relatively short period of time. This behaviour, known as sedentary lifestyle, may be related to a higher risk of cardiovascular disease, osteoporosis, obesity, anxiety, pressure ulcers and many other illnesses. As a consequence, there has been great interest in developing non-invasive and unobtrusive measurement techniques for a variety of health care-monitoring applications, such as for blood oxygen saturation, stress levels, electrocardiograms and glucose monitoring. In such systems, wearable and flexible electronics technologies may enable monitoring of vital signs, offering significant potential for early screening as well as long-term behaviour modelling.

    In this thesis, large area pressure sensors based on non-conventional materials are proposed and realised by screen printing technique for monitoring sitting postures. The developed pressure sensing system measures distributed pressure when an individual sits on a chair equipped with a pressure sensor array. This technology could provide grounding for the advancement of health-related monitoring systems for both able-bodied and disabled individuals and inform them of their sitting time and sitting posture, and this could be used to establish a sitting pattern. To accomplish this, pressure sensors have been designed using non-conventional flexible electronics. A blend of non-conductive and low-resistance ink is used as pressure-sensitive material to enable the realization of screen-printed sensors. To characterise the performance of the suggested pressure sensor, several tests, such as repeatability, drift and flexibility, are conducted. The sensor has also been exposed to different humidity and temperature conditions in a climate chamber to examine its functionalities.

    A graphical user interface was developed for real-time demonstration of data from distributed pressure points in the form of a pressure map to display the pressure values. Four sitting postures are identified: forward, backward, left, and right leaning. Furthermore, a stretchable pressure sensor is proposed that could follow slight stretching with regard to changes in the shape of the human skin. Machine learning algorithms have been employed to further enhance the sitting posture identification, and accuracy of 99.03% is attained. A standalone embedded system capable of illustrating real-time pressure data has been developed with the potential to be used in portable health monitoring systems. In summary, this work provides a promising framework for measuring pressure distribution and identifying irregular sitting postures that may help to reduce the potential risks of developing health-related issues associated with prolonged sitting time.

    Screen Printed Large Area Sensors for Pressure Distribution Monitoring in Wheelchairs2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    A sedentary lifestyle can induce health related problems including pressure ulcers. Pro­longed sitting inadequacies constitute a risk for pressure ulcer to many individuals, in particular people with disabilities and re­duced mobility. The measurement of distributed pressure and detection of irregular sitting postures are essential in prevention of the risk of developing pres­sure ulcers.

    In this thesis, a screen-printed pressure sensor for a large area is presented, with the objective of measuring the distributed pressure of a seated per­son in a wheelchair. The conductors and interdigital patterns are printed with silver-based ink. A blend of a non-conductive and a low resis­tive ink is used for customized resistance for an optimal sensing range of the pressure sensor. The effect of moisture and temper­ature are realized in an environment chamber. For characterization, other key performance tests such as repeatability, drift and flexibility are carried out. The surface morphology is carried out for structural analysis of printed samples. The sensor data is acquired and processed using an 8-bit ATmega-2560 micro­controller and wirelessly transmitted to a PC for post-processing, storage and analysis. For real-time data presentation of dis­tributed pressure points, a GUI has been developed to display the values ob­tained from the large area sensor. The detection of four sit­ting pos­tures; forward leaning, backward leaning, left leaning and right leaning along with a normal sitting posture is attained. An analysis for stretchable printed tracks has been conducted to investigate the changes in electrical resistance using elon­ga­tion tests, surface morphology and EDS. The optimal curing time and tem­per­ature were investigated to manufacture stretchable conductive tracks.

    In summary, the contributions in this thesis provides an effective approach regarding pressure distribution measurement and recognizing irregular sitting postures for wheelchair users.

    Screen Printed Piezoresistive Sensors for Monitoring Pressure Distribution in Wheelchair2019In: IEEE Sensors Journal, ISSN 1530-437X, E-ISSN 1558-1748, Vol. 19, no 6, p. 2055-2063Article in journal (Refereed)
    Abstract [en]

    Prolonged sitting inadequacies cause pressure ulcer to many individuals, especially to disadvantaged with reduced mobility. The measurement of distributed pressure and detection of irregular sitting postures is essential for preventing the risk of developing pressure ulcer. In this paper, a pressure sensing system capable of recognizing sitting postures by means of measuring interface pressure through printed pressure sensors is presented. A thin and flexible large area sensor is screen-printed using silver flake and carbon particle inks and comprises 16 sensing elements. For the evaluation of practical usability, the sensor characterization is carried out by conducting stability, repeatability, drift and bending tests. The performance of the sensor is checked under varying environmental conditions. Sitting posture detection accuracy above 80 % is achieved using a classification algorithm for four different sitting postures. Pressure distribution is monitored at a scanning rate of 10 Hz. A low power and small form factor of read-out electronics enables a compact packaging inside the seat cushion. The presented sensor design targets smart wheelchairs, but it is extendable to much larger areas, for example to be used in beds. The proposed sensing system would be of a great assistance for caregivers and health professionals.

    A Proposal of Implementation of Sitting Posture Monitoring System for Wheelchair Utilizing Machine Learning Methods2021In: Sensors, E-ISSN 1424-8220, Vol. 21, article id 6349Article in journal (Refereed)
    Abstract [en]

    This paper presents a posture recognition system aimed at detecting sitting postures of a wheelchair user. The main goals of the proposed system are to identify and inform irregular and improper posture to prevent sitting-related health issues such as pressure ulcers, with the potential that it could also be used for individuals without mobility issues. In the proposed monitoring system, an array of 16 screen printed pressure sensor units was employed to obtain pressure data, which are sampled and processed in real-time using read-out electronics. The posture recognition was performed for four sitting positions: right-, left-, forward- and backward leaning based on k-nearest neighbors (k-NN), support vector machines (SVM), random forest (RF), decision tree (DT) and LightGBM machine learning algorithms. As a result, a posture classification accuracy of up to 99.03 percent can be achieved. Experimental studies illustrate that the system can provide real-time pressure distribution value in the form of a pressure map on a standard PC and also on a raspberry pi system equipped with a touchscreen monitor. The stored pressure distribution data can later be shared with healthcare professionals so that abnormalities in sitting patterns can be identified by employing a post-processing unit. The proposed system could be used for risk assessments related to pressure ulcers. It may be served as a benchmark by recording and identifying individuals’ sitting patterns and the possibility of being realized as a lightweight portable health monitoring device.

    Stretchable Pressure Sensor Using Thermoplastic Polyurethane and Conductive Inks2021In: Proceedings of IEEE Sensors, IEEE, 2021, article id 1310Conference paper (Refereed)
    Abstract [en]

    The development of wearable health devices is an emerging technology, and pressure sensors have been widely used in several of these applications. Plenty of research within pressure sensors is focused on tactile sensing and artificial skin. In this paper, a highly flexible and stretchable pressure sensor is presented. The sensor comprises stretchable thermoplastic polyurethane (TPU) film as substrate and stretchable conductive inks as electrodes and sensing material. Screen printing is used to fabricate electrodes and pressure sensing components on TPU sheets. Electrical and mechanical properties of the fabricated sensors indicate good mechanical and electrical stability while retaining pressure sensing properties and marginal deterioration even after 100 elongation cycles. The findings show that the presented stretchable pressure sensor has a great potential for usage on surfaces where bending and stretching will occur while retaining nearly all of its electrical and mechanical capabilities. The proposed sensor may be employed as a wearable device to detect human movements.
