Park, Sangtae; Pannu, Satinderpall S.

The present disclosure relates to a gyroscope that makes use of a shuttle having a first plurality of fingers, a stator having a second plurality of fingers, at least one fixed support structure, and a plurality of flexors for supporting the shuttle for vibratory motion relative to the stator. The fingers of the shuttle are able to move in a vibratory motion adjacent the fingers of the stator without contacting the fingers of the stator. Portions of the fingers of at least one of the shuttle and the stator also make use of a grounded metal material layer to reduce parasitic capacitive coupling between the fingers of the shuttle and the fingers of the stator.
