Abstract
Various systems and methods for sensing are provided. In one embodiment, a sensing system is provided that includes a first electrode array disposed on a proof mass, and a second electrode array disposed on a planar surface of a support structure. The proof mass is attached to the support structure via a compliant coupling such that the first electrode array is positioned substantially parallel to and faces the second electrode array and the proof mass is capable of displacement relative to the support structure. The first electrode array includes a plurality of first patterns of electrodes and the second electrode array includes a plurality of second patterns of electrodes. The sensing system further includes circuitry configured to provide an input voltage to each of the second patterns of electrodes to produce an electrical null position for the first electrode array.
