Claim 6:
7. A micro hemispherical resonator gyroscope, comprising
a micro hemispherical resonator, wherein
the micro hemispherical resonator is fixedly connected to a planar electrode substrate-through a central anchor, and the planar electrode substrate is configured to extract a vibration signal from the micro hemispherical resonator gyroscope;
a gap is provided between both ends of the micro hemispherical resonator and the planar electrode substrate and the gap is configured to implement an electrostatic actuation and capacitive detection of the micro hemispherical resonator gyroscope; and
a geometric center of the micro hemispherical resonator coincides with a geometric center of the planar electrode substrate, and the micro hemispherical resonator gyroscope is manufactured by the wafer-level assembly method of claim 1.
