Claim 0:
1. A vibratory gyroscope comprising:
a primary axis;
a support substrate comprising a substrate primary surface and a resonator support surface, extending substantially perpendicular to the substrate primary surface; and
a hollow shell resonator comprising a resonator inner surface, a resonator outer surface, an inner edge surface, and an outer edge surface, wherein:
the resonator outer surface is opposite of and separated by a wall thickness from the resonator inner surface,
the outer edge surface extends between the resonator inner surface and the resonator outer surface, having an annulus shape, and facing the substrate primary surface,
the inner edge surface is surrounded by the resonator inner surface, positioned closer to the primary axis than the outer edge surface, and facing the substrate primary surface,
the resonator inner surface defines a recessed region having a recessed region opening extending between the outer edge surface and the inner edge surface, having an annulus shape, and facing the substrate primary surface,
the resonator outer surface extends to the inner edge surface or is separated from the inner edge surface by the wall thickness, and
at least one of the resonator inner surface and the resonator outer surface is attached to the resonator support surface of the support substrate adjacent to the inner edge surface.
