ABSTRACT:
The angular velocity sensor includes a container, a sensing element in the container and a viscous fluid between the container and the sensing element. The sensing element is supported by the viscous fluid such as an ER fluid or an MR fluid. The angular velocity sensor detects acceleration of the body in which the angular velocity sensor is installed. The angular velocity sensor controls the viscosity of the viscous fluid depending on the acceleration of a body, by changing a voltage applied to the viscous fluid.
