Angular velocity sensor

Abstract

Embodiments of the invention provide an angular velocity sensor, including a mass body, a first frame disposed at an outside of the mass body, a first flexible part connecting the mass body to the first frame, and a second flexible part connecting the mass body to the first frame. The angular velocity sensor further includes a second frame disposed at the outside of the first frame, a third flexible part connecting the first frame to the second frame, and a fourth flexible part connecting the first frame to the second frame. According to at least one embodiment, the first flexible part is connected to be displaced depending on a movement of the mass body, the second flexible part is fixed to the first frame to rotatably displace the mass body, and the third flexible part is fixed to the second frame to rotatably displace the first frame and is formed in pair which is adjacent and opposite to each other.
