Patent ID: 8378434

Claim:
An electromechanical tilting device comprising a first electrode structure comprising substantially mutually parallel electrodes, a second electrode structure comprising substantially mutually parallel electrodes, wherein the electrodes of the first electrode structure are at least partially interdigitated with the electrodes of the second electrode structure to form overlapping regions defining gaps between the electrodes of the first electrode structure and the electrodes of the second electrode structure within the overlapping regions, and a suspension associated with the second electrode structure configured to define a tilt-containing motion path for rotating the second electrode structure with respect to the first electrode structure about a rotation axis substantially parallel to the electrodes of the first electrode structure and to the electrode the second electrode structure, wherein the rotation axis is positioned so that the rotating changes angles and distances between the electrodes of the first structure within the overlaps and the electrodes of the second structure within the overlaps, and wherein the tilt-containing motion path changes dimensions of the overlapping regions and of the gaps between the interdigitated electrodes.
