A capacitive sensor includes an insulator substrate, a detecting electrode formed on one face of the insulator substrate by arranging a first electric wire to provide a plurality of first annular portions, and a driving electrode formed on the other face of the insulator substrate by arranging a second electric wire to provide a plurality of second annular portions. In a region where the detecting electrode and the driving electrode of the insulator substrate are overlapped with each other as seen in a plan view, the second electric wire is arranged such that a plurality of corner portions of the second annular portion are contained within the first annular portion.

A capacitive transducer includes first and second fixed outer plates, each having fixed electrodes positioned on inner surfaces, and a center plate assembly positioned between the fixed outer plates. The center plate assembly includes a top center plate and bottom center plate. The top and bottom center plates each have an inner section, an outer frame positioned outward of a perimeter of the inner section, a set of springs connecting the outer frame to the inner section, and a center electrode positioned on an outer surface of the inner section. The set of springs has thickness less than each of the inner section and the outer frame. The center electrodes of the top and bottom center plates are connected to become electrically one electrode.

A touch sensor comprises two baseplates arranged at intervals, a first electrode disposed between the baseplates, and a pressure sensing module. Two-dimensional touch control of the sensor is achieved by the first electrode. An insulating material is provided between the module and the first electrode. The module comprises a second electrode based on the insulating material and disposed on a side of the insulating material away from the first electrode, and a third electrode disposed above the other one of the baseplates. The second electrode is not in contact with the third electrode, an air gap is provided between the second and third electrodes, the second and third electrodes are respectively connected to a signal output source. When one of the baseplates close to the second electrode is touched, the air gap changes a spacing to change a self-capacitance signal of the signal output sources.

Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to the implementation and operation of a non-contact displacement measurement technique for cryogenic stabilization in QIP systems.
