摘要： An angular velocity sensor includes a protrusion protruding in a Y′-axis direction and extending in an X-axis direction on a main surface of a rotated Y cut quartz plate, and an excitation electrode and a detection electrode formed on the main surface adjacent to this protrusion. This excitation electrode excites thickness-shear vibration in the X-axis direction on the quartz substrate, exiting vibration on the protrusion. Then, the protrusion is bent and displaced due to Coriolis force acting in a direction orthogonal to the vibration of the protrusion corresponding to a rotation around an Y′ axis. This displacement at the protrusion is applied to the quartz substrate as stress. The detection electrode detects change of this stress, thereby angular speed added to the angular velocity sensor is detected.

摘要： An acceleration sensor having a vibrating body includes: a base fixed to a pedestal; an oscillating arm extended from the base in a beam-like shape, oscillating transversally in a planer direction at a predetermined resonant frequency. Here, the oscillating arm includes: an oscillating block defined by a through hole opened through a thickness direction at a widthwise center of the oscillating arm, the through hole extending in a lengthwise direction thereof; an added mass being a junction of a distal end of the oscillating block defined by the through hole; and an excitation means installed on the oscillating arm. At this time, the oscillating arm is supported by the base and by the added mass, either in a pseudo-dual anchor structure or a single anchor structure. With the above configuration, the acceleration sensor detects a resonant frequency variability of the vibrating body caused by an inertial effect of the added mass under acceleration.
