A preferred rotary actuator includes an actuator assembly having a torque tube formed of a shape memory alloy (SMA), a superelastic NiTinol return spring associated with the torque tube and adapted to bias the torque tube toward an initial position, and a torque tube heating element, especially a thermoelectric device, for switching the SMA to cause rotation to an object connected to the actuator or to generate a torque upon that object. The torque tube (24) includes a proximal end (32) and a distal end (34). The return spring and torque tube are connect...


We claim: 1. An actuator for cycling between first and second positions, comprising: first and second shape memory alloy (SMA) material elements trained to shapes in opposition to one another in their respective austentite phases; at least one heating/cooling device thermally connected to at least one element, each heating/cooling device being capable of simultaneously heating one SMA element while cooling the other; and a locking assembly associated with at least one SMA element. 2. An actuator according to claim 1, wherein each heating/cooling de...
