Abstract
A sensor (10) for determining angular velocity includes one or a plurality of piezoceramic plates (11, 12, 31 to 34), which are suitably oriented with respect to the axis of rotation and execute shear oscillations with the aid of an exciting circuit. If the sensor (10) is located in a rotating system, piezoelectric charges are generated on specific plate surfaces by generated Coriolis forces (K.sub.c). These charges represent a measure of the rotational velocity (.OMEGA.).
