Title
(EN) METHOD FOR MANUFACTURING AN ELECTRICALLY CONDUCTIVE DEVICE MADE OF LIGNOCELLULOSIC MATERIAL
(FR) PROCÉDÉ DE FABRICATION D'UN DISPOSITIF ÉLECTRIQUEMENT CONDUCTEUR EN MATÉRIAU LIGNO-CELLULOSIQUE
Abstract
(EN) A method for the production of an electrically conductive device made of lignocellulosic material comprises the following steps: - impregnating (S10) the lignocellulosic material with at least one filling compound so as to produce a composite substrate; and - depositing (S12) at least one conductive layer on at least one surface of the composite substrate so as to produce an electrically conductive device. Use of an electrically conductive device thus produced, particularly as a tactile interface.
(FR) Un procédé de fabrication d'un dispositif électriquement conducteur en matériau ligno-cellulosique comprend les étapes suivantes : - imprégnation (S10) du matériau ligno-cellulosique par au moins un composé de remplissage de sorte à produire un substrat composite; et - dépôt (S12) d'au moins une couche conductrice sur au moins une surface du substrat composite de sorte à produire un dispositif électriquement conducteur. Utilisation d'un dispositif électriquement conducteur ainsi réalisé notamment comme interface tactile.
