Abstract: An oscillatory gyroscope is described with decoupled drive and sense oscillators and reduced cross-axis sensitivity. The gyroscope is fabricated using a plasma micromachining process on standard silicon wafers. The electrical isolation of the drive and sense functions of the gyroscope, contained within the same micromechanical element, reduce cross-coupling while obtaining high inertial mass and high sensitivity.
