Electronic materials • • • • • •
Actuators Sensors Computational devices Communication Power (generation, storage) Connectors
• All of these can be more or less integrated into textile materials
Non-electronic active textiles • Cyclodextrine, microencapsulation
• Antibacterial coatings (e.g. proteins) • Curtains with one-way viewing
Phase-Change Materials (PCM) For extreme temperature conditions Can 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-res graphics 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), mainly used for medical applications • Affect the acoustic properties of a room with 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. • By Margareta Zetterblom & PLAY
Tactile feedback/attention
Together with Arméns markstridsskola and FMV Master work by Johan Andersson and Annika Lundberg
Sensors • Discrete eletronics vs. Integrated into textiles – Add-on vs. Add-in
• 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 generator Temperature differance induces electric current (Seebeck effect) Using e.g. body heat to gerenate electric energy Wristwatch, 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…
