Abstract

The present invention provides a bistable actuator device formed by thin films for generating mechanical motion in response to an electronic control signal. The present invention combines a thin film bistable mechanical member (1) under compressive stress with piezoelectric thin film force elements to generate improved force and displacement properties in the actuator device. Applications of the bistable actuator device include, but not limited to, a micro pump, and an electronic switch or relay.
