Patent ID: 6984332

Claim:
A method for manufacturing a micro-electro-mechanical gyroscope, comprising: providing a piezoelectric substrate; forming a pattern having a plurality of apertures therethrough; and fabricating, using said pattern, a plurality of features on said substrate, said features comprising: a resonator transducer for creating a first surface acoustic wave on said surface; a pair of reflectors for reflecting said first surface acoustic wave to form a standing wave within a first region of said surface between said pair of reflectors; a structure within said region, wherein a Coriolis force acting upon said structure creates a second surface acoustic wave; and a first sensor transducer disposed on said surface for sensing said second surface acoustic wave; and a second sensor transducer disposed on said surface for sensing a residual surface acoustic wave from a second region of said surface that is free of any structure that said Coriolis force can act upon, and for providing an output indicative of said residual surface acoustic wave.
