Abstract
An embodiment of a capacitive sensor array may comprise a first plurality of sensor elements and a second sensor element comprising a main trace that intersects each of the first plurality of sensor elements to form a plurality of intersections. A unit cell may be associated with each of the intersections, and each unit cell may designate a set of locations nearest to a corresponding intersection. A contiguous section of the main trace may cross at least one of the plurality of unit cells.
