Flexinol® is a trade name for shape memory alloy actuator wires. Dynalloy Flexinol® Wire is made of nickel-titanium allowing these small diameter wires to contract like muscles when electrically driven. If used within the guidelines then obtaining repeatable motion from the wire for tens of millions of cycles is reasonable.
