Capacitive sensors having improved response symmetry

An input device, comprising:

• a first plurality of sensor electrodes disposed substantially parallel to each other;
• a second plurality of sensor electrodes disposed substantially perpendicular to the first plurality of sensor electrodes, an aerial extent of the first and second sensor electrodes defining a sensor region;
• a plurality of routing traces disposed within the sensor region of the input device, wherein a first sensor electrode included in the first plurality of sensor electrodes is coupled to a first routing trace included in the plurality of routing traces, and the first routing trace is routed through a second sensor electrode included in the first plurality of sensor electrodes;
• and
• a processing system coupled to the first plurality of sensor electrodes and the second plurality of sensor electrodes via the plurality of routing traces.

A method of input sensing with an input device, the method comprising:

• driving a first plurality of sensor electrodes disposed substantially parallel to each other for capacitive sensing;
• receiving resulting signals from a second plurality of sensor electrodes disposed substantially perpendicular to the first plurality of sensor electrodes while the first plurality of sensor electrodes are being driven for capacitive sensing, the first and second sensor electrodes having an aerial extent defining a sensor region;
• receiving, in a processing system, the resulting signals via a plurality of routing traces disposed within the sensor region and coupled to the second plurality of sensor electrodes, wherein a first sensor electrode included in the first plurality of sensor electrodes is coupled to a first routing trace included in the plurality of routing traces, and the first routing trace is routed through a second sensor electrode included in the first plurality of sensor electrodes;
• and
• determining positional information based on the resulting signals.
