The Department of Textile Technology at the Indian Institute of Technology, Delhi (India) http://www.iitd.ac.in/cgi-bin/nph-p/http/10.116.2.57/textile/upload/xUE_761.htm Good overview of smart textile research at Delhi University. Smart textiles divided into three categories:

1.	Active  The fabric has a specific quality and doesn't respond to the environment. For example: an insulated coat that will keep you warm or fire retardant clothing that remain irrespective of fire presence in the surrounding.
2.	Passive  For example: a chemical warfare suits which could capture any toxin in their active carbon adsorbent layer but allow inert gasses to pass.
3.	Very Active  Textile which adapt their functionality to changing environment automatically. Textile material change properties or shape with time or environment stimuli. In this area new concepts are being investigated where electronics, phase change materials, and stimuli sensitive polymers are being integrated/converted into textile structures for active functionality.

Shape Memory Alloy: http://www.textile.t4tech.com/technologies.asp#

SMA devices can perform the functions of switches, actuators, valves and other devices, where the activation of devices by temperature change is desirable. Shape change is predictable and reproducible to fine tolerances and considerable savings over conventional devices in the areas of weight, complexity and need for power supplies can be made. Application Areas: SMA devices have potential application in fire detectors, cooling and heating systems or any situation where heat change can be used to trigger a mechanical action.

Thermal

At IIT Delhi they are developing fabrics that can provide a thermal balance between the heat generated by the body and the heat released into the environment. research based on the absortion and release of heat by different materials.

http://www.iitd.ac.in/cgi-bin/nph-p/http/10.116.2.57/textile/pcm.htm

It's hard to say how far they got and what's been accomplished.

At SWL (Smart Wear Lab, Tampere University of Technology, Finland)they are working on Personal Protective Clothes in the context of radiation, wind and wetting effects. It is an ongoing research and there is not a lot of information on what's actually happening.

I haven't checked their links with other institutions yet. Might be more revealing, perhaps.

Toughing

Polymet: http://www.textile.t4tech.com/technologies.asp#

Variations of basis materials, coating metals and designable surface structures allow for composite materials which are resistant to tearing, conductive, resistant to temperature and almost chemically resistant and thus result in innovative new products. POLYMET is a flexible solution for innovative surface structures. Completely new surfaces are created by galvanotechnical metallizing of high-tech fabrics. By metallizing - enveloping coating - fabrics based on an endless three dimensional polymer structure are furnished with specific, geometric and microporous metal structures up to micrometer dimensions with high stability. This new compound material is applicable in microchemical systems due to its variably designable metal coating.

Sensors

Piezofoils http://www.textile.t4tech.com/technologies.asp#

The sensor foils are suitable for applications in the areas of dynamic force, pressure, motion and temperature measurements up to high frequencies. Some realised examples are: flow sensors, IR sensors, vibration and puls pressure sensors, keyboards, tactile sensors in robotics, and ultrasonic sensors. Piezoelectric actuators are suitable for employing large displacements with small forces, e.g. for damping or amplification of oscillations of leight-weight structures, optical deflector components, miniature positioning devices or fans.

Power Sources

Sucking energy out of the drain. It's a cool idea! http://www.nature.com/nsu/040223/040223-10.html

Microbes in wastewater could make a handy household battery. Bacteria that eat organic matter are already present in waste water. and flushing the toilet could help supply your home with electricity, thanks to a device developed by US researchers: microbial fuel cells.

They have shown that electricity can be generated from domestic wastewater, which is full of organic matter from cooking, cleaning or sewage. If the lab prototype can be scaled up to a household version, the team says it could save energy and treat waste for every home.

iSun™ - BattPak™

http://windupradio.com/icp/isun.htm

The BattPak™ acts as a 6V/12V power source, a AAA/AA NiCad or NiMh? battery recharger, and a power charger for portable electronics which feature their own internal rechargeable batteries.

The BattPak™ slides under the iSun™ into its docking bay permitting the portable power user to complete power independence, day or night, wherever they may be. The BattPak? will act as a 6V/12V power source, a AAA/AA NiCad or NiMh? battery recharger, and a power charger for portable electronics which feature their own internal rechargeable batteries.

Not on the market either, not at least until 2005. Instead of using rechargeable batteries, you will be able to use fuel cells instead, see FuelCell. The article talks about the fuel cells not as alternatives to rechargeable batteries, but as a complementary technology.
