Abstract
A capacitive sensor array may comprise a plurality of column sensor electrodes and a plurality of row sensor electrodes. The column sensor electrodes may be capacitively coupled with the row sensor electrodes to form a plurality of unit cells each including an intensity center identifying a location of greatest capacitance sensitivity between a row electrode and a column electrode. An axis of a set of row sensor electrodes may cross at least a portion of each row electrode in the set, and the intensity centers associated with the row electrodes in the set may be staggered on alternating sides of the axis. For each of the plurality of unit cells, a distance between the intensity center of the unit cell and a nearest intensity center of another unit cell at a perimeter of the unit cell may be at least 0.7 times the height of the unit cell.
