Abstract

One embodiment of a capacitive sensor array may comprise a first plurality of sensor elements and a second sensor element comprising a main trace, where the main trace 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 the corresponding intersection. A contiguous section of the main trace may cross at least one of the plurality of unit cells. Within each unit cell, the second sensor element may comprise at least one primary subtrace branching away from the main trace.
