Patent ID: 7782161

Claim:
A microelectrical mechanical actuator, comprising: a substantially planar substrate defining first and second opposing sides; a first conductor electrically connected to the first side of the substrate and electrically connected to a first source at a first electrical potential; a second conductor electrically connected to the first side of the substrate and electrically connected to a second source at a second electrical potential; a first conductive coil having a first end and a second end, wherein the first end is fixedly coupled to the first side of the substrate and is in electrical communication with the first conductor and the second end is in electrical communication with the second conductor such that electrical current can be selectively conducted through the first coil so as to create a first magnetic flux within the first coil; and a magnet located adjacent the second side of the substrate and providing a second magnetic flux that opposes the first magnetic flux of the first coil to force the first coil to expand and move relative to the substrate.
