  • Patent number: 9000656
    Abstract: This disclosure provides systems, apparatus, and devices and methods of fabrication for electromechanical devices. In one implementation, an apparatus includes a metal proof mass and a piezoelectric component as part of a MEMS device. Such apparatus can be particularly useful for MEMS gyroscope devices.
