Revision as of 21:29, 30 November 2011

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
[http://www.amazon.com/SolarActive%C2%AE-Changing-Embroidery-Thread-Starter/dp/B0050D6UX8 Solar Active thread]
[http://www.amazon.com/Sensitive-Color-Changing-9x6mm-500pcs/dp/B004LCVCA0/ref=sr_1_cc_2?s=arts-crafts&ie=UTF8&qid=1322701136&sr=1-2-catcorr 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

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/
