摘要： A rotation-type decoupled MEMS gyroscope including a drive body movable about the X-axis, a sensing body movable about the Z-axis, a medium body moving together with the drive body about the X-axis and the sensing body about the Z-axis. The drive body is fixed on a substrate by a first torsion spring torsion-deformed about the X-axis, and the medium body is connected to the drive body by a first bending spring bending-deformed about the Z-axis. The sensing body is connected to the medium body by a second torsion spring torsion-deformed about the X-axis and fixed to the substrate by a second bending spring bending-deformed about the Z-axis. If angular velocity is applied relative to the Y-axis while the drive body vibrates in a certain range about the X-axis by a driving electrode, the sensing body rotates about the Z-axis by the Coriolis force and a sensing electrode senses the rotation.
