The invention belongs to the technical field of micro-electro mechanic systems (MEMS), and relates to a piezoelectricity driven capacitance detecting two-axis gyroscope. According to the invention, a lower surface of a gyroscope oscillator with a shape of a round disc, a wheel spoke or a honeycomb is connected to a supporting cylinder. The other end of the supporting cylinder is fixed on a lower pole plate. The lower pole plate is fixed on a carrier. An upper pole plate signal detecting electrode is positioned on a lower end surface of the upper pole plate. A lower pole plate signal detectingelectrode is positioned on an upper end surface of the lower pole plate. The upper pole plate, the lower pole plate and the gyroscope oscillator are assembled, and differential capacitance is formed for detecting output signals. According to the invention, a special modality of a round disc, a wheel spoke or a honeycomb shape is adopted in the gyroscope oscillator, the detection is driven by piezoelectricity effect, and the detection is carried out by using capacitance. Therefore, angular velocities parallel to the upper and the lower surfaces of the gyroscope oscillator can be sensitively detected. According to the invention, with an MEMS micromachining technology, two-axis detection can be realized, the machining technology is easy to realize, the reliability is high, the energy consumption is low, the impact resistance is high, and the gyroscope can operate well in severe environments.
