Abstract:
A MEMS electrostatic actuator that provides 5 degrees of freedom (5-DOF) motion is disclosed. The actuator comprises of an inner, a middle, and an outer MEMS structures that are nested with respect to each other. Each of the structures comprise of a plurality of rotors and stators. The rotors further comprise a plurality of moving capacitive electrodes which engage with a plurality of fixed capacitive electrodes in the stators to provide a variety of translational and rotational motions.
