Claim:
1. A capacitive sensor array, comprising: a first set of sensor electrodes; and a second set of sensor electrodes, wherein each of the second set of sensor electrodes intersects each of the first set of sensor electrodes to form a plurality of unit cells each corresponding to a pair of sensor electrodes including one of the first set of sensor electrodes and one of the second set of sensor electrodes, wherein a first trace pattern of a first pair of electrodes forming a first unit cell of the plurality of unit cells is different from a second trace pattern of a second pair of electrodes forming an adjacent unit cell of the plurality of unit cells, wherein a first electrode, from the first set of sensor electrodes, is included in the first pair of electrodes to form the first unit cell and in the second pair of electrodes to form the adjacent unit cell, wherein a first shape of the first electrode that forms the first unit cell is different from a second shape of the first electrode that forms the adjacent unit cell, wherein the first unit cell includes a different number of trace branches than the adjacent unit cell, and wherein the first unit cell is nearer than the adjacent unit cell to an edge of the capacitive sensor array.
