  • 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.
  • Magnetic paint - she makes it herself.
  • Thermo chromic film
    • picture of wall paper with thermo chromic film flowers
  • 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.
  • 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
  • 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
  • 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
  • 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
  • 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
    • Sewable EL inverter made by Ben Zatlin???
  • 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 in between 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
