Abstract

L’invention concerne une électrode électrochimique (100) qui comprend :- un empilement (200) délimité par deux faces principales (201, 202) et un contour (203) reliant lesdites faces, l’empilement comprenant, entre ses faces principales, une alternance de feuillets de graphène (300) et de couches diélectriques (400) et de sorte que chaque feuillet de graphène soit intercalé entre deux couches diélectriques, le bord des feuillets de graphène étant en partie exposé à l’environnement extérieur au niveau d’une section, dite section active (204), du contour, ladite section active (204) formant une zone électro-chimiquement sensible de l’électrode électrochimique,- une ou plusieurs électrodes, dites électrodes de contact (500), contactant électriquement les feuillets de graphène (300), et destinées à collecter un signal électrique résultant d’une réaction électrochimique susceptible de se produire au niveau de la section active (204). Figure pour l’abrégé : figure 1 .
