Abstract
An input device sensor includes proximity receiver electrodes on a first single layer, force receiver electrodes on a second single layer, and transmitter electrodes configured to transmit a transmitter signal. Each transmitter electrode includes proximity transmitter segments linearly arranged on the first single layer and separated by the proximity receiver electrodes. The transmitter electrodes further each include force transmitter segments linearly arranged on the second single layer and separated by the force receiver electrodes, the force transmitter segments connecting adjacent proximity transmitter segments in the proximity transmitter segments. The input device sensor further includes a first ground shield on the first single layer, the first ground shield shielding the force receiver electrodes from the proximity transmitter segments. The input device sensor further includes a ground plane, and a compressible layer interposed between the second single layer and the ground plane.
