Abstract
An actuator comprising an actuator body, a shape memory member mounted on the body and a heating element in heat exchange relationship to the shape memory member. By activating the heating element, sufficient heat is generated to heat the shape memory member to its transition temperature so that it deforms from a distorted shape toward its original shape.
