1. A method of sensing rotation, comprising the steps of:

  • vibrating a first pair of piezoelectric tines at a first frequency; and

    sensing piezoelectric voltages in a second pair of tines parallel to and interconnected with said first pair of tines, said voltages induced in the second pair of tines by the vibration of said second pair of tines being caused by the vibration of said first pair of tines and the rotation of said first and second pair of interconnected tines.
