Abstract
One embodiment of a capacitive sensor array may comprise a first plurality of sensor elements and a second sensor element capacitively coupled with each of the first plurality of sensor elements. The second sensor element may further comprise a first main trace and a second main trace, where the first main trace and the second main trace intersect each of the first plurality of sensor elements, and where each of the main traces cross at least one of a plurality of unit cells associated with the second sensor element. The second sensor element may also comprise a connecting subtrace electrically coupled to both the first main trace and the second main trace, and within each unit cell, at least one primary subtrace branching away from the first main trace or the second main trace.
