摘要：An actuator for at least translationally or linearly moving an object from a firstposition to a second position displaced from the first position is disclosed. In oneembodiment, the actuator includes a strip of shape memory alloy configured as a coilwound about a first rotatably-fixed member, the strip having first and second endportions, the first end portion being interconnectable to the first rotatably-fixed memberand the second end portion being operatively associated and/or interconnectable withthe object to be moved, and a heating assembly adapted to heat at least a portion of thestrip of shape memory alloy from a first temperature corresponding to the strip being ina martensitic state to a second temperature corresponding to the strip being in anaustenitic state, the second temperature being above a martensitic/austenitic
transformation temperature of the shape memory alloy. Such heating of the strip to theaustenitic state results in at least radially-outward and arcuate movement of the secondend portion of the strip which, in turn, may move the object translationally.
