摘要
A thermal bend actuator includes: an active beam for connection to drive circuitry; and a passive beam mechanically cooperating with the active beam, such that when a current is passed through the active beam, the active beam expands relative to the passive beam, resulting in bending of the actuator. The passive beam has first and second layers with the second layer sandwiched between the first layer and the active beam. The first layer is thicker than the second layer.
