Electromechanical system having a dielectric movable membrane and a mirror

摘要

A microelectromechanical (MEMS) device includes at least one electrode, a first reflective layer, and a movable reflective element. The movable reflective element includes a flexible dielectric layer and a second reflective layer mechanically coupled to the flexible dielectric layer. The flexible dielectric layer flexes in response to voltages applied to the at least one electrode to move the reflective element in a direction generally perpendicular to the first reflective layer.
