发明名称 Piezoelectric transducers and inertial sensors using piezoelectric transducers
摘要 An inertial sensor includes driving piezoelectric transducers for enabling an oscillation of a resonator, sensing piezoelectric transducers for enabling a detection of a movement of the inertial sensor, and piezoelectric compensating elements substantially equidistantly among the driving and the sensing piezoelectric transducers, wherein the compensating elements and the resonator form corresponding capacitors having capacitive gaps, and wherein, during the oscillation of the resonator, changes in electrostatic charges stored in the capacitors are measured with the compensating elements and are modified so as to modify the oscillation of the resonator.
