A gyroscope comprises a piezoelectric substrate having a surface. Disposed on
the
surface are a resonator transducer, a pair of reflectors, a structure such as a
metallic dot, and a sensor transducer. The resonator transducer creates a first
surface acoustic wave on the surface. The pair of reflectors reflects the first
surface acoustic wave to form a standing wave within a region of the surface between
the pair of reflectors. The structure is disposed on the surface within the region,
wherein a Coriolis force acting upon the structure creates a second surface acoustic
wave. The sensor senses the second surface acoustic wave and provides an output
indicative thereof.
