Claim Text:
1. A micromechanical device comprising: a substrate; a plurality of support structures anchored to the substrate; a micromechanical structure supported by the substrate via the plurality of support structures and configured for overtone resonant vibration relative to the substrate, the overtone resonant vibration having a set of nodal points along the micromechanical structure; and a plurality of electrodes supported by the substrate and spaced from the micromechanical structure by respective gaps, the plurality of electrodes comprising multiple drive electrodes configured relative to the micromechanical structure to excite the overtone resonant vibration with a differential excitation signal, and further comprising multiple sense electrodes configured relative to the micromechanical structure to generate a differential output from the overtone resonant vibration; wherein:
