1. A sensor mat configured for being disposed around a steering wheel frame, the sensor mat comprising:

  • a base substrate supporting at least one shielding circuit, at least one sensing circuit, and a plurality of layers of insulating material, wherein the layers of insulating material define a plurality of surfaces in the sensor mat, and wherein the layers are stacked about an axis extending from the base substrate and through the plurality of surfaces;

    one or more of the sensing circuits printed with conductive ink onto one of the plurality of surfaces of the insulating material;

    one or more shielding circuits printed with the conductive ink onto another of the surfaces of insulating material within the sensor mat,wherein the shielding circuits and the sensing circuits are configured in corresponding pairs of one shielding circuit and one sensing circuit, wherein the shielding circuits overlap at least one area within the plurality of surfaces of the insulating material on which a respective sensing circuit is printed and such that the shielding circuits and the sensing circuits are separated by at least one of the layers of the insulating material.
