1. A sensor, comprising:
a sensing area comprising a grid of force sensing elements, where force sensing elements of the grid of force sensing elements are connected between respective row electrodes of a group of row electrodes and respective column electrodes of a group of column electrodes;
an AC signal source operatively connected between column multiplexing circuitry and a control circuit; and
an analog switch operatively connected between the control circuit and the sensing area, wherein the analog switch facilitates alternating, for respective force sensing elements being scanned, between a first scan of the sensing area via the AC signal source and a second scan of the sensing area via a DC voltage source.
