The invention is based on an electrode system for measuring the concentration of an analyte in vivo, comprising a counterelectrode (2) with an electrical conductor (2a), a working electrode (1) with an electrical conductor (1a), on which an enzyme layer (5 ), which contains immobilized enzyme molecules for catalytic conversion of the analyte, and a diffusion brake which slows the diffusion of the analyte from body fluid surrounding the electrode system to enzyme molecules.n n n According to the invention, it is provided that the enzyme layer (5) is designed in the form of several fields which are arranged on the conductor (1a) of the working electrode (1) at a distance from each other. |
