  • MEMS actuator device deployment
    Patent number: 8941192
    Abstract: A method for making an actuator device includes forming a substantially planar structure having a stage resiliently supported for movement within a plane of the structure, an actuator coupled to an outer periphery of the stage and operable to apply a force acting in the plane and tangentially to the stage when actuated, the actuator comprising a fixed frame and a moving frame resiliently supported for reciprocal movement relative to the fixed frame by a motion control flexure, and an outer frame surrounding and supporting the stage and the actuator. The moving frame is moved to a deployed position that is coplanar with, parallel to and spaced apart from the fixed frame at a selected distance, and the moving frame is then fixed at the deployed position for substantially rectilinear, perpendicular movement relative to the fixed frame.
