Abstract
A micro-machined actuator for use in, among other things, sensors and data storage devices. The actuator includes a stator wafer and a micro-mover positioned adjacent to the stator wafer. Between the stator wafer and the micro-mover are electrodes that are set to specified voltages and that emanate electric fields that position the micro-mover relative to the stator wafer. Also between stator wafer and the micro-mover are bumpers that prevent the electrodes from coming into contact with each other.
