Abstract:
1. A touch sensor comprising: a plurality of drive electrodes comprising a plurality of drive electrode structures each coupled to an adjacent drive electrode structure by a first strip of conductive material; and a plurality of sense electrodes comprising a plurality of sense electrode structures each coupled to an adjacent sense electrode structure by a second strip of conductive material, the plurality of sense electrode structures being formed on a same layer as the plurality of drive electrode structures, the first or second strip of conductive material comprising one or more conductive crossovers that each couple two drive electrode structures to each other or couple two sense electrode structures to each other; a microcontroller configured to alternately reverse the roles of the plurality of drive electrodes and the plurality of sense electrodes by: wherein at least a portion of one or more of the conductive crossovers is disposed in a separate layer from the drive or sense electrodes.
