Abstract:
1. An electromechanical device comprising: a substrate; a movable element over the substrate, the movable element comprising an electrically conductive deformable layer and a reflective element mechanically coupled to the deformable layer, the reflective element including a reflective surface, the reflective surface spaced from the deformable layer along a direction generally parallel to the reflective surface; and an actuation electrode under at least a portion of the deformable layer and disposed laterally from the reflective surface, the movable element responsive to a voltage difference applied between the actuation electrode and the deformable layer by moving in a direction towards the substrate, wherein a stationary portion of the device is configured to act as a stop for movement of the movable element, the movable element responsive to the voltage difference applied between the actuation electrode and the deformable layer by moving from a first position in which a portion of the movable element is not in contact with the stationary portion to a second position in which the portion is in contact with the stationary portion.
