Claim Text:
1. A control device for an electrical circuit integrated on a substrate made of polymeric material, incorporating carbonaceous conductive structures which define at least one track having improved electrical conductivity properties with respect to the substrate, which control device includes an operating area able to be acted on by a user and having a pressure-deformable structure adapted to disturb the electrical properties of said integrated track by a piezo-resistive effect, wherein said integrated conductive track includes at least one linear segment which has a winding progression at said operating area, wherein said integrated conductive track includes a thermally modified zone, where an electrical conductivity effect may occur, and which is arranged entirely on a same side with respect to a neutral plane of the operating area of the device, and wherein said integrated conductive track includes at least one linear segment having a winding progression at said operating area, and which includes for the most part sections of trajectory having a predominant component oriented in a plane of deformation of the operating area, which are subjected to a stressing differential such that said conductive structures experience deformation which causes a variation in electrical resistivity.
