<verbatim> 1.) Conductive paint - wire glue is cheap, but takes a long time to cure (8-12 hours) and isn't conductive until it's cured.

 - She uses super glue to protect the wire glue after it's cured.

- nickel print - She doesn't use resistors with conductive paint because it's highly resistive.

2.) Magnetic paint - she makes it herself.

3.) UV reactive thread and beads Solar Active thread UV reactive beads

4.) Temperature reactive material - fabric, pigment, and paint - You can get the pigment from http://www.paintwithpearl.com/

5.) Thermo chromic film - picture of wall paper with thermo chromic film flowers

6.) Mylar - not a "smart" material, but still a cool material - you get it from the inside of potato chip bags

(an aside)Copper tape is very useful. She uses it a lot.

7.) moldable materials - polymorph (or polycaprolactone) is plastic that melts in hot water, can be molded, and then is hard nylon once it cools

 - can be melted any number of times

- sugru a playdoh that cures at room temperature - mold making putty cures in 10 minutes and then can take high temperatures

8.) Quantum Tunneling Composite - smart flexible polymer (rubber-like) - near perfect electrical insulator - 4mm square and 1.5mm thick can pass 10 amps when squeezed - conductivity affected by pressure - also magnetic - currently not being made due to patent issues - but you can get it in pill form currently - used to be able to get in fabric form Peratech

9.) Endlighten - edge diffusing material - http://www.youtube.com/watch?v=evGALmP4F8s - price depends on size and goes up with bigger sheet because you need a higher grade plastic

10.) Conductive plastics - plastics with metal particles (graphite)

 - comes in sheets

- stretch sensors with metal in stretchable plastic

 - resistance decreases with stretch

- conductive polyester rope

 - resistance increases with stretch because the fibers align

- conductive acetate

 - thin and clear with a film of metal a few atoms thick

11.) Shape memory polymers - you expose it to high heat and then shape it - after it cools down, you can unshape it, then heat it up slightly and it will return to it's shaped form

12.) EL wire - 1.2mm (angel hair) to 6mm (outdoor grade) thick wire with a phosphorous material in it - comes in sheets - can make your own sheets with conductive sheeting and phosphorous paint - requires an inverter to step up the voltage and has a danger of shock - EL driver Ben Zatlin???

13.) Conductive fabrics - copper tafita - metal iron ons (nickel)

 - very durable
 - nickel lasts longer than the copper

- fabric that has insulators on one side - anti-static material that is pressure sensitive

 - put inbetween two conductive fabrics

- conductive lycra

 - resistance decreases if stretched in one direction, resistance increases if stretched in the other direction

- conductive tape

 - metal traces on fabric that is solderable

- All found at http://www.lessemf.com/

14.) Conductive food - candy coated in silver or gold - pumpkins as capacitive sensors - resistor jelTone http://www.flickr.com/photos/ranjit/5879592536/ </verbatim>
