1. A sensor system, comprising:
- a plurality of sensors, each sensor including piezoresistive fabric and two or more conductors in contact with the piezoresistive fabric; and
sensor circuitry configured to activate and receive signals from the sensors via the conductors, each signal representing a force acting on a corresponding sensor, the sensor circuitry having associated memory and being further configured to determine a force value for each signal using sensor data stored in the memory, the sensor data including a plurality of stored values for each sensor, the plurality of stored values representing a response of the corresponding sensor to a range of forces.
