Abstract
A common capacitive touch sensor may have a two dimensional array of transparent conductive strips going from edge to edge on a substrate layer or sheet of a touch sensor. According to some aspects, there is provided a capacitive touch sensor device including a substrate layer and a plurality of resonant circuits. Each resonant circuit includes an electrode, and each resonant circuit has a respective resonance frequency that is unique within the plurality of resonant circuits. The electrodes of the resonant circuits are distributed on the substrate layer. A controller for a touch sensor is also provided that includes a signal generator to drive at least one plurality of resonant circuits, where each resonant circuit has a respective resonance frequency. The signal generator is tunable to generate input signals at each of the resonance frequencies. The controller also includes a detector.
