Touch sensor pattern

A capacitive touch-sensing system comprising:

• a capacitive sensor array comprising a plurality of intersections between a plurality of first sensor elements and a second sensor element, wherein each of the plurality of intersections is associated with a unit cell, the second sensor element comprising, within each unit cell, a first primary trace crossing the unit cell and second primary trace crossing the unit cell, a first secondary trace connecting the first primary trace and the second primary trace, and a first tertiary trace branching away from the first secondary trace between the first primary trace and the second primary trace, wherein an area of the first sensor element is greater than an area of the second sensor element within the unit cell;
• and
• a capacitance sensor coupled to the capacitive sensor array, wherein the capacitance sensor is configured to measure a mutual capacitance for each of the plurality of intersections between the plurality of first sensor elements and the second sensor element.

A capacitive sensor array comprising:

• a first plurality of sensor elements;
• and
• a second sensor element intersecting each of the first plurality of sensor elements to form a plurality of intersections, wherein each of the plurality of intersections is associated with a unit cell, wherein the unit cell designates a set of locations nearest a corresponding intersection, the second sensor element comprising, within the unit cell, a first primary trace crossing the unit cell and second primary trace crossing the unit cell, a first secondary trace and a second secondary trace each connecting the first primary trace and the second primary trace, a first tertiary trace branching away from the first secondary trace between the first primary trace and the second primary trace, and a second tertiary trace branching away from the second secondary trace between the first primary trace and the second primary trace, wherein an area of one of the first plurality of sensor elements is greater than an area of the second sensor element within the unit cell.
