Patent ID: 8901944

Claim:
A capacitive sensor array, comprising: a first plurality of sensor elements each comprising a core trace, wherein for each sensor element of the first plurality of sensor elements, the core trace of the sensor element is wider than any other trace of the sensor element; and a second sensor element comprising a main trace, wherein the main trace crosses the core trace of each of the first plurality of sensor elements at a corresponding bridge to form a plurality of intersections each associated with a unit cell, 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 a contiguous section of the core trace of each of the first plurality of sensor elements crosses at least one of the plurality of unit cells, and wherein, within each unit cell, the second sensor element comprises at least one primary subtrace branching away from the main trace.
