1. A touch sensor panel comprising:
a first layer of a first conductive material including a plurality of electrically isolated electrodes including a first electrode having a first width and a first length longer than the first width, a second electrode having a second width and a second length longer than the second width, and a gap free of the first conductive material separating the first electrode and the second electrode, each of the first electrode and the second electrode configured to be driven with a stimulation signal; and
a second layer of a second conductive material including a third electrode, a fourth electrode, and a first floating conductor, the third and fourth electrodes configured to be capacitively coupled with the first and second electrodes, respectively, to generate touch signals for mutual capacitance touch sensing, wherein the first floating conductor includes
a first portion of the first floating conductor formed over less than a full first width of the first electrode, and
a second portion of the first floating conductor formed over less than a full second width of the second electrode.
