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.'
