1 The integration of smart textiles enabling a non- invasive approach in monitoring the user’s vitals and activities Prof. Lieva Van Langenhove Department of textiles

2 Components Sensors and actuators Communication devices Energy supply Data processing Connections and interconnections  Miniaturisation, packaging, integration, transformation into textiles  Concepts and electro/photo active materials

3 Why textiles? All around Versatile Light weight Large contact area with body Comfortable Easy to use

4 Electro conductive textiles Stainless steel Kevlar coated with KnittedWovennon woven polypyrrol copper gold

5 Effects from nano to macro

6 Conductive knitted textiles as sensor TextrodesRespibelt

7 EMG monitoring Myography for 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 Any mechanism that changes conductivity is exploitable for sensors Carbon nanotubes for conductivity Fibre expansion changes conductivity: Extension Heating Humidity Chemicals (E. Devaux ENSAIT)

10 Humidity control Sensors: Absorption: Thermoresponsive gels Supporting design

11 Optical sensor Signal A’ Smart interface Signal B Textile fibre Sensor/ Processing unit Signal A filter

12 Smart interface: active dyes skin pH days Skin pH-variation after burn wound L. Van der Schueren, K. De Clerck

13 Communication Within components Between components in a suit ‣ Conductive fibres ‣ Optical fibres With the wearer: keyboard, display Wide environment: Inductive (embroidery) Antenna (printing)

14 Data processing: Motherboard

15 Fibre transistor Conductive core: gate Insulating coating Semiconductor coating Electrode: source Electrode: drain Semiconductor Source Insulator Gate Drain OFET: organic field effect transistor

16 Coating: from dip to padding

17 OFET textile integration Weaving structure Right patterns Right contacts No falso contacts Stable contacts 100µm Gate source drain

18 PEDOT based battery

19 Printed battery: results

20 Energy from light: PV Solar bags

21 Energy from motion: piezo electrics Deformation leads to E field Needs large surface, no thickness PVDF Challenges: Materials Concepts Production (poling) Electrode Piezo electric layer Electrode

22 Smart textile research Based on (semi)conductive materials and structures Smart dyes Conceptual design Modelling and simulation Manufacturing Testing
