ABSTRACT:
An electrostatic actuator for adjusting a spacing. A first body has an electrically conducting surface, and a second body has a body surface separated by the spacing from the electrically conducting surface. A conductor layer and an actuator electrode are recessed in the second body, and an electrode face faces the electrically conducting surface across the spacing. The actuator electrode comprises a semi-insulating material with a combination of electrical resistivity and thickness which prevents shorting of the conductor layer to the electrical conducting surface through a dielectric breakdown in the spacing.
