Nanotubes Make Synthetic Skin Feel Your Pain

Carbon nanotubes can conduct sensations through artificial skin back to the brain, making prosthetic limbs feel like the real thing. A nanotube like this one, delicately balanced on top of gold filaments, is threaded through a rubbery polymer. This nanotube-infused polymer generates electricity in response to pressure… » 1/08/08 12:00pm 1/08/08 12:00pm
