Abstract
A slider lifter including a support structure, a flexure arm and a resilient means cantilevered from the support structure, and a shape memory alloy element operatively connected between the support structure and the resilient means, wherein the shape memory alloy element has a martensitic condition and an austenitic condition. The shape memory alloy element in one of the martensitic and austenitic conditions cooperates with the resilient means to elastically deform the flexure arm from an undeformed position to a deformed position. The shape memory alloy element in the other of the martensitic and austenitic conditions cooperates with the resilient means to both move away from the fexure arm, thereby allowing the flexure arm to return towards its undeformed position. It is most preferred that when the resilient means moves away from the flexure arm, the flexure arm and the resilient means are not in contact. This allows the flexure arm to return to its completely undeformed position.
