Integral capacitive sensor array

摘要

A capacitive sensor array wherein the plurality of electrodes and the power and data lines communicating with the electrodes are formed from a single dielectric substrate. One face of the substrate is a grounded area, with the electrodes and power and data lines formed from the substrate on the opposite face. A ground connector connects the grounded areas on the two faces without a need to penetrate the substrate. The substrate is flexible, and the power and data lines are die cut from a portion of the substrate to form an integrated cable.
