  1. 1. Screen Printed Large Area Sensors for Pressure Distribution Monitoring in Wheelchairs

    Författare :Jawad Ahmad; Johan Sidén; Henrik Andersson; Xavier Crispin; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 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. LÄS MER

  3. 2. Thermoelectric properties of conducting polymers

    Författare :Olga Bubnova; Xavier Crispin; Magnus Berggren; Alan Kaiser; Linköpings universitet; []
    Nyckelord :Thermoelectric generation; Seebeck coefficient; conducting polymers; thermoelectric efficiency.;

    Sammanfattning : According to different sources, from forty to sixty percent of the overall energy generated in the world today is squandered in waste heat. The existing energy conversion technologies are either close to their efficiency limits or too costly to justify their implementation. LÄS MER
