Abstract
A micro-electromechanical actuator (7) includes a substrate (2). Drive circuitry is positioned on the substrate (2). An active beam member (10) is anchored to the substrate (2) at one end and electrically connected to the drive circuitry. The active beam member (10) defines an electrical heating circuit that is spaced from and overlies the substrate (2) to heat resistively and expand when a current from the drive circuitry is set up in the active beam member (10). A passive beam member (12) is also anchored to the substrate (2) at one end and electrically isolated from the drive circuitry. The active beam member (10) is interposed between the substrate (2) and the passive beam member (12). A longitudinally extending lever arm (6) is fast at one end to an opposite end of the active (10) and passive (12) beam members, such that expansion and subsequent contraction of the active beam member (10) causes reciprocal movement of the lever arm (6) away from and towards the substrate (2). A working member is fast with an opposite end of the lever arm.
