The VSG-4 MEMS vibrating-structure gyroscope from Silicon Sensing Systems Ltd., Plymouth, U.K., uses a tiny vibrating silicon ring to detect angular velocity through the Coriolis effect. The sensor's digital closed-loop control of ring vibration amplitude and frequency results in improved integrity, accuracy, and reliability. An evaluation board is available, which integrates the gyro with a 2-axis accelerometer, resulting in a typical sensor cluster for electronic stability applications. Sensors are intended for use in yaw rate sensing in vehicle stability control systems, among other applications.
