Abstract:
An actuator (100) taking advantage of ponderomotive forces to enhance its electromechanical performance as a function of input energy. An actuator (100) may include a first conductive layer (102) residing on a first electret layer (101).

The optical MEMS device (200) can be a shutter for selectively affecting the flow of light through the package (300). A plurality of optical MEMS device (200) may be located within a single package (300) because the optical paths for the MEMS devices (200) can be substantially parallel to each other.
