Problems solved by technology

However, these other conventional miniature gyroscopes present some varying problems
For example, these conventional miniature gyroscopes may have one or more of the following problems: due to the coupling of the motion of the driving unit including the driving object and the sensing unit including the sensing object, it is difficult to match the driving and sensing frequencies, and the sensing object or Sticking between the sending unit and sensing electrodes, performance degradation due to weak buoyancy, slowed sensing motion, sensing pattern deformation or relatively complex fabrication process

Abstract

A rotary gyroscope includes a base plate, an intermediate structure, including a driven element floating over the base plate as supported by a driving supporter radially extending therefrom, the driven element performing an oscillating motion with respect to a first axis, which is vertical to a center plane thereof, a driving electrode driving the driven element , and a sensing element disposed in the driven element and connected to the driven element by a sensing connector to oscillate together with the driven element and concurrently to perform a sensing motion with respect to a third axis, which is vertical to the first axis and any second axis, which is parallel to a center plane, due to a Coriolis force when an angular velocity is inputted from the second axis, and a cover covering the intermediate structure and having a sensing electrode to detect the sensing motion of the sensing element.

Description

technical field [0001] The present invention relates to a gyroscope for detecting angular velocity using rotational resonant motion of an object moving at a regular angle. In particular, the present invention relates to a rotating gyroscope capable of sensing multiple angular velocities corresponding to multiple axes in a plane. Background technique [0002] Generally, the gyroscope detects the rotational angular velocity by converting the displacement of the object caused by the Earth's rotation deflection force (Coriolis force) into a change in capacitance, based on the following principle, that is, when an object oscillating or rotating in the direction of the first axis is moved from the vertical When a force rotating at a constant angular velocity is applied in the direction of the first axis and the second axis, the earth rotation deflection force acts on the object in the direction of the third axis perpendicular to the first axis and the second axis. [0003] Such g...
