Abstract
A touch sensor may include thin, conductive wires as at least some of the sensor electrodes. Some or all of the conductive wires may be metal wires. The sensor electrodes may not be noticeable to a human observer. In some such implementations, the sensor electrodes may be laid out in a pattern and/or grouped to create a spatial gradient. Some such implementations involve spatial interweaving, spatial interposing and/or length modulation of sensor electrodes. Such implementations can create a spatial gradient such that fewer rows and columns are required to provide a touch sensor panel with a given level of accuracy.
