Abstract
A microstructure for a vibratory gyroscope has a ring portion supported in such a fashion to allow substantially undamped, high-Q radial vibration. The ring portion is electrically conductive and comprises a charge plate for a plurality of radially disposed charge conductive sites around its perimeter for sensing radial displacements thereof. The ring, its support and charge conductive sites are formed within sacrificial molds on one surface of a conventional silicon substrate which may comprise a monolithic integrated circuit.
