Abstract:
An inertial sensor includes a movable mass spaced apart from a surface of the substrate. The movable mass is adapted for motion about a rotational axis positioned between first and second ends of the movable mass in response to a first force imposed upon the movable mass in a first direction that is perpendicular to the surface of the substrate. The inertial sensor further includes a damping system configured to limit motion of the movable mass in a second direction perpendicular to the first direction. The damping system includes a first damping structure coupled to the movable mass, a second damping structure adjacent to the first damping structure, the first and second damping structures being spaced apart from the surface of the substrate, and a spring structure interconnected between the movable mass and the second damping structure.
