1. A sensor system for integration with a glove, comprising:

  • a plurality of digit assemblies, each digit assembly being configured for alignment with a corresponding finger of the glove, each digit assembly including a flexible dielectric substrate, a plurality of sensor trace groups on a first surface of the flexible dielectric substrate, routing traces connected to each sensor trace group, the routing traces being adjacent a second surface of the flexible dielectric substrate opposite the first surface, and a plurality of patches of piezoresistive fabric, each patch being in direct contact with and forming a knuckle sensor with a corresponding one of the sensor trace groups; and

    circuitry configured to activate and receive a knuckle signal from each knuckle sensor on each digit assembly using the corresponding routing traces, each knuckle signal representing lateral stretching of the corresponding patch of piezoresistive fabric caused by bending of a knuckle in the corresponding finger of the glove, the circuitry also being configured to generate digital information using the knuckle signals, the digital information representing movement of a hand in the glove.
