Solid State Angular Rate Sensor

Applications:

Inertial Sensors - Tilt Measurement

This solid-state angular rate sensor has a sensing mechanism consisting of piezoelectric bender elements mounted to a rigid base in a “tuning fork” configuration (as shown below). The two drive elements are resonantly driven in opposite directions. When a rotation occurs, the momentum stored in the vibrating elements causes an out-of-plane bending force (called Coriolis force) which is demodulated to accurately represent the rotation rate.

These angular rate sensors have no moving parts, no detectable hysteresis, quick startup, and are low cost since the sensors are more electronic than mechanical.
