  1. The integration of smart textilesenabling a non-invasive approach in monitoring the user’svitalsandactivities Prof. Lieva Van Langenhove Department of textiles

  2. Components • Sensors andactuators • Communication devices • Energy supply • Data processing • Connections andinterconnections • Miniaturisation, packaging, integration, transformationintotextiles • Concepts andelectro/photoactivematerials

  3. Whytextiles? • All around • Versatile • Lightweight • Large contact areawith body • Comfortable • Easy to use

  4. Electro conductivetextiles Stainless steel Kevlarcoatedwith KnittedWoven non woven polypyrrolcopper gold

  5. Effectsfrom nano to macro

  6. Conductiveknitted textiles as sensor TextrodesRespibelt

  7. EMG monitoring Myographyfor stress measurement Contactless Professional use EMG sensors embroidered laminated (www.context-project.org)

  8. Pressure sensors Double layer fabric: No contact contact Quantum tunneling effect

  9. Anymechanismthatchangesconductivity is exploitablefor sensors • Carbon nanotubesforconductivity • Fibreexpansionchangesconductivity: • Extension • Heating • Humidity • Chemicals (E. Devaux ENSAIT)

  10. Humiditycontrol • Sensors: • www.Biotex-eu.com • Absorption: • Thermoresponsive gels • Supporting design
