Abstract
A trim element includes at least one support layer having an inner face and an outer face and at least one functional layer of carbon material extending over at least part of the inner face and/or over at least part of the outer face of the support layer. A part of the functional layer defines a pattern having at least one conductive area of carbon material and at least one non-conductive area formed by a through-opening in the functional layer, the conductive area being powered by a current source electrically connected to the conductive area, the pattern forming at least a part of an electrical circuit arranged to perform a function.
