dc.description.abstract A Coriolis-based bulk acoustic wave gyroscope includes a center-supported resonating element with capacitively-coupled drive, sense, and control electrodes. The resonating element has a first substantially solid or perforated region which is connected to the center-support by a second region characterized by a plurality of spokes or beams. When operating in a resonance state, the first region undergoes a bulk acoustic mode of vibration while the second region undergoes a flexural mode of vibration. Energy losses associated with the flexural mode of vibration reduce the overall quality factor (Q) at high resonance frequencies creating a large bandwidth and a fast response time without needing vacuum.
