The angular velocity is converted to, and output as, an electrical signal.Ĥ. The motion of a pair of sensing arms produces a potential difference from which angular velocity is sensed. When the gyro is rotated, the Coriolis force acts on the drive arms, producing vertical vibration.ĥ. Normally, a drive arm vibrates in a certain direction.ģ. Here, we explain how this works, using as an example Epson 's double-T structure crystal element.ġ. Vibration gyro sensors sense angular velocity from the Coriolis force applied to a vibrating object. How Angular Velocity Sensing Works (in Vibration Gyro Sensors) NOTE: Every company uses a different structure. Vibration gyro sensor manufacturers are using a variety of materials and structures in an effort to devise compact, high-accuracy gyro sensors that have good characteristics, including:
