Smart Paper
Some eggheads at MIT are working on a smart paper which has wires, sensors, and computer chips embedded inside the paper. There are multiple other entities working on this type of technology to provide cheap, flexible, and intelligent electronic devices (effectively eliminating the bulky size of our phones and ipods), but MIT’s method of using conductive ink seems to really be able to make much bigger strides in reducing cost and complexity.
