The second electrode is coupled to a second voltage source. The mobile element includes a third electrode coupled to a third voltage source. A steady voltage difference between the first electrode and the third electrode is used to tune the natural frequency of the structure to a scanning frequency of an application. An oscillating voltage difference between the second electrode and the third electrode at the scanning frequency of the application is used to oscillate the mobile element. In one embodiment, the mobile unit is a mirror.

Abstract: A micro-electro-mechanical system (MEMS) device includes a mirror having a top surface with trenches, a beam connected to the mirror, rotational comb teeth connected to the beam, and one or more springs connecting the beam to a bonding pad. The mirror can have a bottom surface for reflecting light. The mirror can include a top flange and a bottom flange joined by a web, wherein the top and the bottom flanges form the top and the bottom surfaces, respectively. The rotational comb teeth can have a tapered shape. Stationary comb teeth can be interdigitated with the rotational comb teeth either in-plane or out-of-plane. Steady or oscillating voltage difference between the rotational and the stationary comb teeth can be used to oscillate or tune the mirror.

Abstract: A mirror device includes a mirror, an anchor, and a spring coupling the mirror to the anchor. The anchor and/or mirror can define one or more rows of holes adjacent to the coupling location of the spring. The natural frequency of the device can be adjusted by removing material between the perimeter of the mirror/anchor and the outermost holes, and between adjacent holes in the same row. Another mirror device includes a mirror, anchors, and springs coupling the mirror to the anchors. The natural frequency of the device can be adjusted by decoupling one or more springs coupling the mirror to the anchors. The mirror of both devices can includes one or more sacrificial portions. The natural frequencies of the both devices can also be adjusted by trimming the sacrificial portions.
