- 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.
- wire glue is cheap, but takes a long time to cure (8-12 hours) and isn't conductive until it's cured.
- Magnetic paint - she makes it herself.
- UV reactive thread and beads
- Temperature reactive material
- fabric, pigment, and paint
- You can get the pigment from http://www.paintwithpearl.com/
- 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
- polymorph (or polycaprolactone) is plastic that melts in hot water, can be molded, and then is hard nylon once it cools
- 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
- 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
- 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
- http://www.lessemf.com/
- plastics with metal particles (graphite)
- 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
- All found at http://www.lessemf.com/
- Conductive food
- candy coated in silver or gold
- pumpkins as capacitive sensors
- resistor jelTone http://www.flickr.com/photos/ranjit/5879592536/
