1. A sense array comprising:
- a first set of sense elements comprising 1st, 2nd, and 3rd sense elements disposed substantially parallel to each other, wherein the first set of sense elements is electrically connected together at a first end of the sense array;
a second set of sense elements comprising 4th, 5th, and 6th sense elements disposed substantially parallel to each other, wherein the second set of sense elements is electrically connected together at a second end of the sense array opposite the first end; and
a third set of sense elements comprising 7th, 8th, and 9th sense elements disposed substantially parallel to each other, wherein the 1st sense element extends between the 5th and 6th sense elements, the 2nd sense element extends between the 6th and 7th sense elements, the 3rd sense element extends between the 7th and 8th sense elements, and the third set of sense elements is electrically connected together at the second end of the sense array.
