Abstract:
1. An electromechanical device comprising: a substrate; an actuation electrode; and a movable element between the substrate and the actuation electrode, the movable element including a deformable layer and a reflective element each being between the substrate and the actuation electrode, the deformable layer spaced from the reflective element along a direction generally perpendicular to the reflective element, wherein the movable element is configured to be selectively switched among at least a first state having a first spectral reflectance being a first color, a second state having a second spectral reflectance being a second color, and a third state having a third spectral reflectance being a black state, wherein the first state includes the reflective element in a relaxed position, wherein the second state includes the reflective element in a first actuated position, and wherein the third state includes the reflective element in a second actuated position, wherein the reflective element is movable to the second actuated position upon application of a voltage difference between the reflective element and a second actuation electrode, and wherein the reflective element is movable to at least one of the first actuated position and the second actuated position upon application of voltage potential differences both between the reflective element and the actuation electrode and between the reflective element and the second actuation electrode.
