Patent ID: 8236141

Claim:
An industrial roll, comprising: a substantially cylindrical core having an outer surface and an internal lumen; a polymeric cover circumferentially overlying the core outer surface; and a sensing system comprising: a plurality of sensors at least partially embedded in the cover, the sensors configured to sense an operating parameter of the roll and provide signals related to the operating parameter, wherein each of the plurality of sensors comprises: a first electrode overlying the top surface of a substrate and a second electrode underlying the bottom surface of the substrate, wherein the first electrode overlies the top surface of the substrate and the second electrode underlies only a portion of the bottom surface of the substrate, thereby forming a gap adjacent the bottom surface and a side surface of the substrate; a first sheet of conductive material attached to the first electrode and the side surface of the substrate and extended in a first direction away from the bottom surface of the substrate; and a second sheet of conductive material attached to the second electrode and extended in a second direction away from the bottom surface of the substrate, the second direction being opposite the first direction; and a processor operatively associated with the sensors that processes signals provided by the sensors.
