  • Abstract
    We demonstrate the first accelerometer with a resonant strain gauge displacement transducer fabricated in a wafer-scale encapsulation process. Co-fabrication of this device with ultra-stable resonators enables detection of acceleration, and measurement of temperature (for compensation), along with generation of the timing reference for acceleration measurement.
