Abstract
The gyroscopic sensor has a bell-shaped resonator which is fixed along its axis on a substrate. It has a circular edge lying in a plane perpendicular to the axis and at a distance from the point where the resonator is fixed. The substrate carries detection and excitation electrodes that co-operate with the resonator. The detection electrodes are sensitive to an axial component of resonator vibration and the energization electrodes cause vibration at resonance by exerting axial forces.
