  • Patent number: 8117912
    Abstract: In a angular rate sensor, a weight and a base are connected directly through piezoelectric bimorph detectors and piezoelectric bimorph exciters each having a bent portion. When acceleration is applied to the weight, the weight is displaced so as to deform the piezoelectric bimorph detectors. Due to this deformation, charges generated in the piezoelectric bimorph detectors are detected so as to detect acceleration. If an angular rate is applied to the weight when the weight is vibrated by the piezoelectric bimorph exciters, Coriolis force is generated in the weight so as to deform the piezoelectric bimorph detectors. Due to this deformation, charges generated in the piezoelectric bimorph detectors are detected so as to detect the angular rate.
