Intel is working on a new "smart fabric" which is actually a swarm of nanobots. Millions of microscopic spheres covered in electromagnetic actuators would flow into whatever shapes a control computer may command. (Think of the shapeshifting Terminator T-1000 .) Of course, this technology is still in the simulation phase, but it is estimated that a protype may be five years away.
Researchers at Northwestern University have developed a prototype of a robotic whisker system which detects not only the presence of an object but its shape and texture as well.
