Introduction



• The National Institute for Working Life, Leif Sandsjö

• Facilitate longterm ambulatory monitoring

• 2006, 6+6 month project

• Co-operation between The Swedish School of Textiles and Biomedical Engineering, University Hospital Umeå

• Recording of Heart Rate and Electromyographic Signals using textile sensors




• Lena Berglin, PhD project

• Laboratory equipment in woven, knitted, coated, laminated and assembly technologies

• Textile sensors for medical and industrial applications

• How will Smart Textile affect textile technology

• Special interest in weaving and braiding

Biomedical Engineering, University hospital Umeå



• Stefan Karlsson, Urban Wiklund, Marcus Karlsson, Tomas Bäcklund

• Research support and development for the hospital

• Research

• Education at Umeå University

EMG result



• Sensitive measurement

• Further improvements necessary

Concluding Remarks



• Smart Textiles - a system

• Application is central

• Applied research links different disciplines in an interdisciplinary area

Future Outlook



• Interface between textile and electronics - Axon in France

• EMG system

• Contact less electrodes in Co-operation with Umeå and Physics at Chalmers

• Clinical tests

Future Outlook



• New weaving technology, multilayer with independent layers

• Braiding technology

• Assembling Technology

• Increase the number of researchers in the textile group
