ELECTROMECHANICAL DISPLACEMENT SENSOR

A displacement sensor measures capacitance between a rotor-stator pair. The displacement sensor includes a plurality of stators coupled to a first object. The plurality of stators is oriented parallel to an axis of motion between the first object and a second object. The displacement sensor further...

Summary:A displacement sensor measures capacitance between a rotor-stator pair. The displacement sensor includes a plurality of stators coupled to a first object. The plurality of stators is oriented parallel to an axis of motion between the first object and a second object. The displacement sensor further includes a plurality of rotors coupled to the second object. The plurality of rotors is oriented parallel to the axis of motion. Each rotor of the plurality of rotors is aligned with and configured to receive a corresponding stator of the plurality of stators to create a respective rotor-stator pair. Capacitance between the rotor-stator pairs change as a function of position of the first object relative to the second object along the axis of motion. An amount of displacement of the first object relative to the second object is determined based in part on the capacitance values.
