Shape-Memory Wire Prosthetic Hand

Shape-Memory Wire Prosthetic Hand
Mar-26-15
A prosthetic hand that relies on shape-memory wires instead of complicated mechanisms could one day offer a more flexible, affordable and lighter alternative to today's prosthetic limbs.

Instead of motor-driven cables, the prosthetic hand developed by the team at Saarland University features an array of shape-memory nickel-titanium alloy wires. These wires have been arranged in bundles that will become shorter when heated with an electrical current and then return to their original length when cooled. The team used bundles of tiny wires with a great deal of surface area instead of single, large wires, which allows the response to the change in temperature to be very quick and results in smooth finger movements with a high tensile force.
