Each of the transmitters can transmit a different signal on more than one of the row conductors. Row groups can be formed by having one of the signals transmitted on a plurality of row conductors, while other signals are also transmitted on the row conductors. This can increase the sensitivity area for a sensor device and further noise present on the sensor device. ## Claims ### Claim 1 A sensor device, comprising: a plurality of first conductors; a plurality of second conductors positioned in proximity to the plurality of first conductors such that a touch event proximate to the sensor device causes a change in coupling between at least one of the plurality of first conductors and at least one of the plurality of second conductors;
