Abstract
A thermal microactuator is provided that can be deflected in multiple positions. The actuator has a hot arm and a cold arm coupled together at their distal ends suspended above a reference plane of a substrate. A potential difference is applied across the hot arm so that a current circulates through the hot arm but not the cold arm.
