摘要： A thermal bend actuator comprising: (a) a pair of electrical contacts positioned at one end of the actuator; (b) an active beam connected to the electrical contacts and extending longitudinally away from the contacts, the active beam defining a bent current flow path between the contacts; and (c) a passive beam fused to the active beam. When a current is passed through the active beam, the active beam heats and expands relative to the passive beam, resulting in bending of the actuator. The active beam comprises a resistive heating bar having a relatively smaller cross-sectional area than any other part of the current flow path. Heating of the active beam is concentrated in the heating bar.
