Abstract
A yaw rate detector and method of detecting yaw rate. The detector includes a sensor surrounded by a uniformly distributed gel-like material. The gel-like material is retained in a certain shape by a pair of parallel surfaces. The pressure of the gel-like material is affected by centrifugal force, which is sensed by the sensor. The sensor simultaneously detects pressure changes in the gel-like material on opposite sides of the sensor, which permits the detector to sense the angular velocity of rotation of the sensor. The sensor is a semi-conductor pressure sensor formed on a circuit substrate.
