Abstract
A component for the passenger compartment of a motor vehicle includes a rigid supporting body, made of plastic material, an outer upholstery skin, made of plastic material, and a padding body made of foamed plastic material, which is set between the rigid body and the outer upholstery skin. The rigid body and the outer skin have portions formed by a polymeric material with carbon-based nanofillers, which have respective inner surfaces facing the padding body, which include one or more paths where said polymeric material with carbon-based nanofillers has been rendered electrically conductive by laser irradiation to define one or more electrical circuits, and one or more piezoresistive areas where the polymeric material has been rendered piezoresistive by laser irradiation to define one or more electrical switches, which can be activated by exerting a localized pressure on the outer upholstery skin.
