Abstract
An embodiment of a capacitive sensor array may comprise a first set of sensor electrodes each comprising one or more large subelements and a second set of sensor electrodes each comprising one or more small subelements. In one embodiment, each of the small subelements may be smaller than any of the large subelements, and the first set of sensor electrodes and the second set of sensor electrodes are formed from a single layer of conductive material. In one embodiment, the surface area of the capacitive sensor array may be divisible into a grid of N×M unit cells, wherein each of the N×M unit cells contains one of the large subelements and k of the small subelements, where k is greater than or equal to 2.
