Title (EN) CHIPLESS RFID PRINTING METHODS
(FR) PROCÉDÉS D'IMPRESSION RFID SANS PUCE
Abstract:
(EN) With the purpose of having RFID tags that are cheap to produce and that are environmentally friendly, it is disclosed a method and a system to manufacture chipless RFID tags. The method and system comprises printing a conductive track on a carbon-based substrate and selectively heating the substrate on the parts comprising the conductive track. The printing of the conductive track envisages using an ink comprising at least one of a metal carbide, a metal boride or a metal nitride.
(FR) La présente invention a pour objet d'avoir des étiquettes RFID qui sont bon marché à produire et qui sont respectueuses de l'environnement. À cette fin, la présente invention concerne un procédé et un système permettant de fabriquer des étiquettes RFID sans puce. Le procédé et le système comprennent l'impression d'une piste conductrice sur un substrat à base de carbone et le chauffage sélectif du substrat sur les parties comprenant la piste conductrice. L'impression de la piste conductrice prévoit l'utilisation d'une encre comprenant un carbure métallique et/ou un borure métallique et/ou un nitrure métallique.
