Abstract[English]
Alternating electric fields (e.g., TTFields) may be applied to a subject's body using one or more electrode assemblies that includes a sheet of anisotropic material, at least one layer of conductive material disposed on the front face of the sheet of anisotropic material, and an electrode element positioned behind the sheet of anisotropic material. The electrode element has a front face disposed in electrical contact with the rear face of the sheet of anisotropic material. The sheet of anisotropic material spreads both heat and current out in directions that are parallel to the front face of the sheet, which eliminates or at least minimizes hot spots on the electrode assembly. This in turn makes it possible to increase the current without exceeding a temperature safety threshold (e.g., 41° C).[French]
Des champs électriques alternatifs (par exemple, des champs TT) peuvent être appliqués au corps d'un sujet à l'aide d'un ou de plusieurs ensembles électrodes qui comprennent une feuille de matériau anisotrope, au moins une couche de matériau conducteur disposée sur la face avant de la feuille de matériau anisotrope et un élément d'électrode positionné derrière la feuille de matériau anisotrope. L'élément d'électrode présente une face avant disposée en contact électrique avec la face arrière de la feuille de matériau anisotrope. La feuille de matériau anisotrope propage à la fois la chaleur et le courant dans des directions qui sont parallèles à la face avant de la feuille, ce qui élimine ou au moins réduit au maximum les points chauds sur l'ensemble électrode. Ceci permet à son tour d'augmenter le courant sans dépasser un seuil de sécurité de température (par exemple, 41 °C).
