Abstract:
1. A gyroscope comprising: a driving fixed electrode being fixed; a driving displacement electrode being opposite to the driving fixed electrode, and being able to be displaced in a first direction; an inertial mass being connected to the driving displacement electrode, being displaced in the first direction according to the first directional displacement of the driving displacement electrode, and being displaced in a second direction when an angular rate is applied; a sensing displacement electrode being connected to the inertial mass, and being able to be displaced in the second direction according to the second directional displacement of the inertial mass; and a sensing fixed electrode being opposite to the sensing displacement electrode and being fixed; wherein the driving displacement electrode and the inertial mass can be movable in the second direction and are connected by a folded spring having no fixture shaft, and the sensing displacement electrode and the inertia mass can be movable in the first direction and are connected by a folded spring having no fixture shaft.
