1. A sensor system, comprising:
- a flexible piezoresistive fabric substrate having a shape of a portion of an article of footwear, the piezoresistive substrate having top and bottom surfaces;
an array of sensors, each sensor including two conductive traces, both of the two conductive traces for each sensor being printed, screened, or deposited directly on a same one of the surfaces of the piezoresistive substrate, each sensor being positioned on the substrate to align with a region of the exterior of a human foot; and
sensor circuitry configured to energize the sensors to generate sensor signals, and to receive the sensor signals from the array of sensors, each sensor signal representing a force associated with a corresponding one of the sensors, the sensor circuitry being further configured to determine a force value for each sensor signal using calibrated sensor data representing a response of the corresponding sensor.
