  • Physical quantity sensor
    Patent number: 8770025
    Abstract: A physical quantity sensor includes a beam-like vibrating body and a fixing part supporting both ends of the beam-like vibrating body. A driving element is formed on a central portion of the beam-like vibrating body, and feedback elements are formed on both ends. A physical quantity acting on the beam-like vibrating body is detected by causing natural vibration in the beam-like vibrating body and detecting a natural frequency of the vibrating body. This enables reliable detection of a physical quantity, such as a strain or load, acting on an object.
