TLDR
In this article, a micromachined inertial sensor with a single proof-mass was used to measure angular rates about three axes with single drive motion and linear accelerations about the three axes.
Abstract
A micromachined inertial sensor (200) with a single proof-mass (201) or measuring 6-degree-of-motions. The single proof-mass (201) includes a frame (202), an x-axis proof mass section (212a, 212b) attached to the frame by a first flexure, and a y-axis proof mass section (218) attached to the frame (202) by a second flexure (228a, 228b). The single proof-mass (201) is formed in a micromachined structural layer and is adapted to measure angular rates about three axes with a single drive motion and linear accelerations about the three axes.
