ABSTRACT:
A thermal bend actuator, having a plurality of elements, is provided. The actuator comprises a first active element for connection to drive circuitry and a second passive element mechanically cooperating with the first element. When a current is passed through the first element, the first element expands relative to the second element, resulting in bending of the actuator. One of the plurality of elements is comprised of a porous material.
