  • Angular acceleration sensor
    Patent number: 5574221
    Abstract: Seismic inertias are attached to the ends of the arms of elastic plate. Piezoelectric elements are adhered to the upper surfaces of the arms and the elastic plate is supported in the center by a support. When rotation force is applied to the arms of the elastic plate, the arms bend towards opposite direction. The piezoelectric elements are suppressed or extended by the elastic force, thereby they generate electric signals. Rotation directions and angular acceleration velocity can be detected by processing those signals.
