Claim:
1. A sensor system, comprising: piezoresistive fabric having a first side and a second side opposite the first side; a first substrate in contact with the first side of the piezoresistive fabric, the first substrate having a plurality of conductive routing traces and a plurality of conductive trace groups formed thereon, the conductive routing traces, the conductive trace groups and the piezoresistive fabric forming a two-dimensional sensor array in which each of the conductive trace groups is near an intersection of a corresponding pair of the conductive routing traces, and forms a sensor in the sensor array with a corresponding portion of the piezoresistive fabric, each of the conductive trace groups including two or more conductive sensor traces having complementary shapes in contact with the first side of the corresponding portion of the piezoresistive fabric; a second substrate in proximity to the sensor array, the second substrate having a surface; and sensor circuitry configured to receive a sensor signal from each of the conductive trace groups, and, using the sensor signals, to generate data representing locations and magnitudes of force relative to the surface of the second substrate resulting from an object in contact with the sensor system.
