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.

An actuator comprising: an actuator body; a shape memory member that deforms from a distorted shape toward an original shape when subjected to a transition temperature, said shape memory member being in said distorted shape; means for mounting the shape memory member on the actuator body so that the shape memory member can deform from said distorted shape toward said original shape; a heating element in heat exchange relationship to the shape memory member, said heating element including at least first and second components capable when activated of interacting exothermically even in the absence of atmospheric air to heat the shape memory member to said transition temperature whereby the shape memory member deforms toward the original shape; and means for activating the first and second components.
