Abstract: This disclosure generally provides an input device, electronic systems and processing system for touch sensing. In one example, an input device for touch sensing includes receiver electrodes and transmitter electrodes arranged in transmitter and receiver electrode columns. Each transmitter electrode within each transmitter electrode column is paired with two adjacent receiver electrodes of a first column of the receiver electrode columns. A first plurality of traces couple a first group of receiver electrodes in the first receiver electrode column, the first plurality of traces not passing between the transmitter and receiver electrodes of the first transmitter and receiver electrode columns. A second plurality of traces coupled a second group of receiver electrodes in the first receiver electrode column, the second plurality of traces passing between one of the transmitter electrodes of the first transmitter electrode column and one of the receiver electrodes of the second group of receiver electrodes.

Abstract: A circular, single-layer sensor electrode pattern for input devices, such as wearable devices, is described. The sensor electrode pattern features transmitter electrodes and receiver electrodes tiled in alternating fashion, such that each receiver electrode is surrounded by transmitter electrodes. The individual sensor electrodes of the described pattern are designed to provide a substantially uniform electrode area size across the sensor. Additionally, the sensor electrode pattern is arranged to be symmetric across both horizontal and vertical axes. The provided characteristics of the sensor electrode pattern leads to a sensor structure having uniform absolute capacitive sensing measurements for all sensor electrodes as well as uniform transcapacitive sensing measurements for all “pixels.”
