Claim:
1. A capacitive sensor array, comprising: a plurality of unit cells, wherein at least one of the plurality of unit cells comprising: a first plurality of sensor elements; a plurality of second sensor elements respectively comprising a main trace and one or more primary subtraces, wherein the one or more primary subtraces is substantially orthogonal to the main trace at a junction between the one or more primary subtraces and the main trace; and a plurality of bridges connecting portions of the first plurality of sensor elements, wherein the main trace intersects the bridges to form a plurality of intersections each associated with the first sensor element, wherein each of the plurality of unit cells designates a set of locations nearest a corresponding intersection, wherein a contiguous section of the main trace crosses at least one of the plurality of unit cells, wherein at least one of the first sensor elements further comprises a plurality of open zones, and each of the open zones are surrounded by the main trace and the one or more primary subtraces of each of the plurality of second sensor elements, wherein each of the open zones is staggered with a nearest adjacent identical open zone of an adjacent identical unit cell.
