Abstract
A capacitive sensor array may include a first plurality of sensor elements and a second sensor element. The second sensor element may include a main trace intersecting each of the first plurality of sensor elements to form a plurality of intersections each associated with a unit cell, where a contiguous section of the main trace crosses at least one of the plurality of unit cells. An area within the unit cell may include at least a portion of one or more primary subtraces branching from main subtrace, a plurality of secondary subtraces branching away from the one or more primary subtraces, and at least one tertiary subtrace branching away from at least one of the secondary subtraces.
