    Abstract: 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.

    Abstract: X type MEMS gyroscope has a first mass vertically vibrating on a substrate and a second mass horizontally vibrating on the substrate. A driving electrode is disposed on the same surface with the first mass. When the first mass vertically vibrates, the second mass vibrates vertically together with the first mass. When angular velocity that is at a right angle to a movement direction of the first mass and the second mass is applied while the first mass is vertically vibrating, the second mass moves as Coriolis force is added to the second mass in a horizontal direction, and a sensing electrode measures displacement of the second mass in the horizontal direction. All moving electrodes and stationary electrodes are disposed on the same surface, and all elements are manufactured by using one mask. Therefore, adhesion between the moving and stationary electrodes is prevented and the manufacturing process is simplified.
