Patent ID: 7334475

Claim:
A micro-electro-mechanical system (MEMS) device, comprising: an oscillating body; a beam, comprising: a proximal end connected to the oscillating body; a distal end extending away from the oscillating body; and a plurality of rotational comb teeth extending from the beam; a plurality of springs coupling the beam to a plurality of stationary pads, wherein the plurality of springs are aligned along a rotational axis and at least one spring is between another spring and the oscillating body; a stationary pad comprising a plurality of stationary comb teeth interdigitated with the plurality of rotational comb teeth, wherein a voltage difference causes a rotation of the oscillating body about the rotational axis; and a bottom layer, comprising: a plurality of mounting pads for supporting the stationary pad and the plurality of stationary pads; and an electrode asserting a physical influence on the rotation of the oscillating body.
