Abstract
Rather than increasing the mass of the structure, the structure in a sensor system suspends its substrate from some mechanical ground. Motion of the substrate relative to the mechanical ground thus provides the movement information. To those ends, the sensor system includes a base, a substrate, and a flexible member suspended from at least a portion of the substrate. At least a portion of the flexible member is capable of moving relative to at least a portion of the substrate. In addition, the flexible member is secured to the base, thus causing the substrate to be movable relative to the base. Moreover, the mass of the substrate is greater than the mass of the flexible member. The substrate and flexible member are configured to interact to produce a motion signal identifying movement of the base.
