Carbonnanotubes

Originating from a DARPA project, researchers at the University of Texas (Dallas) Nano Tech Institute have created hollow carbon filaments, one-one thousandth the diameter of a human hair, which contain “tethered enzymes.”  When these strands are twisted together, an electrical current can simulate muscle movement as the tubes flex. The researchers envision applications in artificial limbs, and perhaps even artificial hearts.  MORE
