Beschreibung
Zusammenfassung:	A quartz vibratory gyroscope comprises a substrate, a quartz cylindrical ring having one end connected to the substrate and an opposite open end, and a radial surface lined with an electrically conductive material, and a pair (or more) of electrodes arranged adjacent opposite sections of the electrically conductive material to electrically induce resonance at the open end of the quartz cylindrical ring, such as by electrostatic actuation or piezoelectric actuation. The same or additional electrode pairs may be used for rotational sensing, such as by capacitive sensing or by piezoelectric sensing.
