Abstract
A MEMS (micro electro mechanical system) actuator with discretely controlled multiple motions comprises bottom layer, stepper plate, support, and motion plate. The multiple motion of the motion plate is generated by the electrostatically actuated stepper plates and geometrically predetermined supports. By introducing the MEMS actuator with discretely controlled multiple motions, simple motion control can be achieved by digital controlling and only single voltage is needed for motion control of the motion plate.
