Abstract
A capacitive sensor array includes a second sensor element intersecting a first sensor element to form an intersection associated with a unit cell. The second sensor element includes, within the unit cell: a first primary trace crossing the unit cell and a 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. An area of the first sensor element is greater than an area of the second sensor element within the unit cell.
