Patent ID: 7859365

Claim:
A micromechanical resonator apparatus, comprising: a substrate; and a resonator apparatus comprising: first and second anchors connected to the substrate; at least one excitation/sense port that is electrically insulated from the substrate, the at least one excitation/sense port comprising a parallel plate capacitive transducer; and a resonator comprising: at least one flexural beam member connected to the first and second anchors, the at least one flexural beam member separated from the substrate and separated from the at least one excitation/sense port by one or more gaps, where the at least one flexural beam member is a moveable electrode for the parallel plate capacitive transducer; and a mass disposed between the first and second anchors, the mass coupled to the at least one flexural beam member between the first and second anchors and separated from the substrate, the mass comprising a grid.
