Abstract
A gyroscope includes a ring-shaped resonator mounted in a housing, and a bottom plate attached to the resonator. A plurality of openings arranged substantially circumferentially on the bottom plate, and a plurality of grooves between the openings. A plurality of piezoelectric elements are located in the grooves. The resonator is substantially cylindrical. The plurality of openings are arranged substantially symmetrically. The piezoelectric elements can be outside the resonator, or inside the resonator. A cylindrical flexible suspension connecting the bottom to the resonator to the ring shaped resonator, wherein an average radius of the cylindrical flexible suspension and the ring shaped resonator, accounting for variation thickness of wall, is the same throughout.
