Claim 11:
12. A method for detecting an object proximate to a touch sensor panel, comprising:
driving a first stimulation signal on a first electrode having a first width and a first length longer than the first width on a first layer of the touch sensor panel, and driving a second stimulation signal on a second electrode having a second width and a second length longer than the second width on the first layer of the touch sensor panel and separated from the first electrode by a gap;
capacitively coupling the object to the first electrode and the second electrode on the first layer of the touch sensor panel at least partially through a first segment of floating conductive material on a second layer of the touch sensor panel;
capacitively coupling the first electrode with a third electrode on the second layer to enable mutual capacitance touch sensing at the third electrode, and capacitively coupling the second electrode with a fourth electrode on the second layer to enable mutual capacitance touch sensing at the fourth electrode, and generating touch signals on the third electrode and the fourth electrode; and
overlapping a first portion of the first segment of floating conductive material with less than a full first width of the first electrode and overlapping a second portion of the first segment of floating conductive material with less than a full second width of the second electrode.
