Bionic hand uses nitinol ‘smart’ wires to mimic muscle fibers

bionic-hand-nitinol-7x4German researchers using nitinol wires have developed a bionic hand that uses the shape-memory alloy to mimic the contraction and relaxation of muscle fibers. When an electrical charge is applied, the nitinol wires contract, just as muscle fibers do. When the charge is turned off, the wires return to their original shape. The wires are strands of nickel-titanium alloy about the width of a human hair.
