An input sensor for an electronic device which includes a touch sensor panel, multiple electrodes and a sensor circuit. The electrodes include multiple regional electrodes and multiple local electrodes. Each regional electrode covers a corresponding region of the touch sensor panel and each local electrode includes multiple pads including one pad located within each of the regional electrodes. The electrodes are distributed so that a touch anywhere across the touch sensor panel is detected by at least one regional electrode and at least one local electrode. A sensor circuit determines a value for each of the electrodes indicating relative change, and compares relative values of the electrodes to identify a location of a touch of the touch sensor panel. The regional electrodes are used to determine a region of a touch and the local electrodes are used to determine a more specific touch location within the determined region.
