Claim Text:
1. A sensor array comprising: a substrate; a first plurality of receive (RX) electrodes and a second plurality of transmit (TX) electrodes, wherein the first plurality of RX electrodes and the second plurality of TX electrodes are interleaved without intersecting each other within a central area in a single layer on the substrate; wherein a first shaped portion of a first RX electrode, of the first plurality of RX electrodes, is connected to a first primary trace of the first RX electrode and a second shaped portion of the first RX electrode is connected to a second primary trace of the first RX electrode; wherein the first shaped portion and the second shaped portion of the first RX electrode are interleaved with a second TX electrode of the second plurality of TX electrodes, thereby forming a single sensor element of the sensor array; wherein the first primary trace of the first RX electrode is routed in a first direction on the substrate through the central area to a first edge of the central area and the second primary trace of the first RX electrode is routed in a second different direction on the substrate through the central area to a second opposite edge of the central area; and wherein the first primary trace of the first RX electrode is coupled to the second primary trace of the first RX electrode outside of the central area.
