Abstract
An angular rate sensor comprises a wafer of silicon etched to form tines with teeth which are interdigitated. The tines are excited into oscillation in the plane of the wafer, by applying suitable drive signals to create electrostatic forces between the tines. Rotation of the tines out of the plane of the wafer is detected by a suitable detector, such as a piezo-resistor on a support of the tines.
