摘要： A MEMS accelerometer package includes multiple cavities such that a change in pressure corresponding to a breach in one or more of the cavities is readily identified based on the output of a pressure-sensitive sensor such as a MEMS resonator. One or more mitigations may be initiated in response to the identification of the change in pressure.

摘要： Provided herein is a vibration-type angular velocity sensor capable of improving detection precision of angular velocities around the Z axis and preventing detection precision of angular velocities around the X and Y axes from deteriorating. A weight 3 is columnar or conic. The outline of an outer peripheral portion of a diaphragm 1 has such shape that a straight portion ST is formed at each of four corner portions of a square. Four vibration exciting electrodes 11 are respectively located in four regions partitioned by a first imaginary line L1 and a second imaginary line L2. Four angular velocity sensing electrodes 13 are respectively located in four regions partitioned by a first imaginary diagonal line CL1 and a second imaginary diagonal line Cl2.
