A Robot Hand with Smart Metal 'Muscles'
From: Medical Design Technology - 03/24/2015

Engineers at Saarland University have taken a leaf out of nature's book by
equipping an artificial hand with muscles made from shape-memory wire. The
new technology enables the fabrication of flexible and lightweight robot
hands for industrial applications and novel prosthetic devices. The muscle
fibers are composed of bundles of ultrafine nickel-titanium alloy wires that
are able to tense and flex. The material itself has sensory properties
allowing the artificial hand to perform extremely precise movements.
