Abstract:
1. A micro-electromechanical systems (MEMS) device, comprising: a first actuator comprising first and second movable plates, each supported on and positioned offset from a substrate, wherein each of said first and second plates is adapted to move with respect to said substrate, said first plate is adapted to move in response to a voltage applied between a first electrode and said first plate, and said first and second plates are mechanically coupled together such that motion of said first plate with respect to said substrate produces motion of said second plate with respect to said substrate and with respect to said first plate; a second actuator comprising a second electrode and a third movable plate, said third moveable plate being supported on, and positioned offset from, said substrate, wherein said third moveable plate is adapted to move with respect to said substrate in response to a voltage applied between said second electrode and said third moveable plate; a fourth plate having a handle portion; wherein said handle portion of said fourth plate is mechanically coupled to said second plate such that motion of said second plate with respect to said substrate produces motion of said fourth plate with respect to said substrate in the same direction as that of said motion of said second plate and said handle portion of said fourth plate is mechanically coupled to said third plate such that motion of said third plate with respect to said substrate produces motion of said fourth plate with respect to said substrate in the same direction as that of said motion of said third plate.
