New textile materials
• Intelligent textiles?• Smart textiles?
• Functional textiles?• Active textiles?• Textiles with dynamic properties?
Electronic materials• Actuators• Sensors• Computational devices• Communication• Power (generation, storage)• Connectors
• All of these can be more or less integrated intotextile materials
Non-electronic active textiles
• Cyclodextrine, microencapsulation
• Antibacterial coatings (e.g. proteins)• Curtains with one-way viewing
Phase-Change Materials (PCM)For extreme temperature conditionsCan be microencapsulated and coated onto textiles
Everything can be an I/O device
• Potentially, all surfaces can be used as displays and/or sensing devices for computers
• Including textiles…
Computer displays everywhere
• Most displays have been optimized for hi-resgraphics and text
Electroluminescense
• EL-wire• EL-sheets
• Typically used for backlighting of LCDs
• Emits light in itself
Chromic materials, dynamic colors• Thermochromic• Photochromic• Electrochromic
• Does not emit light in itself

Adding computer-controlled motion to textiles
• Integrate microactuators into the textile material
• E.g. shape-memory alloys (SMA), mainlyused for medical applications
• Affect the acoustic properties of a roomwith dynamic textiles
• Micro- and macrolevel physical movement• Static electricity, MEMS...?
Mute
• dynamic sound absorbing textiles that clearly change expression and acoustic properties of an environment.
• these properties can also be used to represent information and create new awareness of sound or other local activity.

Sensors• Discrete eletronics vs. Integrated into textiles
– Add-on vs. Add-in
• Biophysical monitoring– Lots of sensors
• Force, elongation– Conductive elastomers
• Capacitive proximity sensors
• Etc..
Physiological monitoring
• Immediate sensing– Pulse– Heart rate– ECG– Fall detection
• Long-term monitoring– Early signs of e.g. Parkinsons– Time for walking stairs etc…– Accelerometers

Energy generation
• Batteries of course
• Mechanical energy (footsteps etc)• Thermal energy, Seebeck effect• Light energy, Photovoltaic effect (photo
cells)
Heel-Strike Generator Using Electrostrictive Polymers (SRI)
Thermoelectric power generatorTemperature differance induces electric current(Seebeck effect)Using e.g. body heat to gerenateelectric energyWristwatch, belt, shirt buttons…
Really integrated electronics
• ”Textile transistors” on yarns and fibers (e.g. FiCom, Arianne)
• Passive components– E.g. inductors
• Electronic matrix for e.g. displays– Electroluminescent– Thermochromic– Electrochormic– LEDs…

Connectors
• Electrically conductive Velcro• Conductive sheets
• Capacitive coupling• Inductive coupling
• Person-area networks• Body-area networks
Weaving with conductiv yarn, carbon and metall wire
The construction
Scalability?
• Larger networks and surfaces
