The invention relates to an item with at least one switching section, wherein the at least one switching section a) comprises a shape memory compound that comprises at least one thermoprogrammable shape memory polymer and particles incorporated therein suitable for heating in an alternating electromagnetic field, wherein the shape memory compound has a heat transfer coefficient h schalt; and b) comprises an insulating area that surrounds the shape memory compound a) and that has a heat transfer coefficient h iso; wherein h iso < h schalt and to a manufacturing method for such an item.
L'invention porte sur un article présentant au moins une partie de commutation, a) une composition à mémoire de forme, qui contient au moins un polymère à mémoire de forme thermoprogrammable et des particules incorporées dans celui-ci, qui sont appropriés à se réchauffer dans un champ électromagnétique alternatif, la composition à mémoire de forme présentant un coefficient de transfert thermique hschalt; et b) une zone isolante, qui entoure la composition à mémoire de forme a) et qui présente un coefficient de transfert thermique hiso, avec hiso < hschalt. L'invention porte également sur un procédé de fabrication d'un tel article.
