Abstract
A sensor electrode pattern configured to enable the detection of multiple input objects concurrently disposed in a sensing region of a mutual capacitance sensor including a plurality of first sensor electrodes oriented along a first axis, and a plurality of second sensor electrodes oriented along a second axis and configured to be capacitively coupled with the plurality of first sensor electrodes. At least one sensor electrode of the plurality of first sensor electrodes is disposed in a configuration forming multiple crossings with a line that is parallel to the second axis. At least two of the plurality of first sensor electrodes or at least two of the plurality of second sensor electrodes are interleaved with each other proximate to the sensing region of the mutual capacitance sensor. The pluralities of first sensor electrodes and second sensor electrodes include transmitter sensor electrodes or receiver sensor electrodes.
