Abstract
An apparatus for driving and sensing motion in a gyroscope including a dielectric mass, an anchor, a spring coupled between the anchor and the dielectric mass, a substrate adjacent the dielectric mass, an insulator layer on the substrate, and a first electrode and a second electrode on the insulator layer. When an alternating current voltage is applied between the first and second electrodes, an electric field gradient is generated in the dielectric mass and causes the dielectric mass to move relative to the anchor. When the dielectric mass has motion relative to the anchor and a voltage is applied between the first and second electrodes, the movement of the dielectric mass generates a current at the first and second electrodes proportional to the motion.
