Abstract:
1. A micro-electromechanical (MEMS) device, comprising: an optically transmissive substrate; an electrode located on the substrate; a deflectable member spaced from the substrate by a first gap and positioned so that the electrode is between the deflectable member and the substrate, the deflectable member configured to deflect from a rest position to an actuated position when electrostatically attracted to the electrode; and an encapsulation membrane comprising electrically conductive material, the encapsulation membrane spaced from the deflectable member by a second gap, the deflectable member being positioned between the optically transmissive substrate and the encapsulation membrane, the encapsulation membrane configured to electrostatically attract the deflectable member when a reset voltage is applied across the encapsulation membrane and the deflectable member, aiding the deflectable member in releasing from the actuated position.
