Abstract: Electrode systems are disclosed for measuring the concentration of an analyte under in-vivo conditions, where such systems include a counter electrode having an electrical conductor, a working electrode having an electrical conductor on which an enzyme layer containing immobilized enzyme molecules for catalytic conversion of the analyte is arranged, and a diffusion barrier that slows the diffusion of the analyte from body fluid surrounding the electrode system to enzyme molecules. The enzyme layer is in the form of multiple fields that are arranged on the conductor of the working electrode at a distance from each other.

Abstract: The disclosure generally relates to continuous monitoring of an analyte by determining its change over time in the living body of a human or animal. A measurement variable value correlating with the desired concentration of the analyte are measured as the measurement signal (zt) and the change over time of the concentration is determined from the measurement signal as the useful signal (yt) using a calibration. A filter algorithm is used to reduce errors of the useful signal, which result from noise contained in the measurement signal. The filter algorithm includes an operation in which the influence of an actual measurement value on the useful signal is weighted using a weighting factor (V).

Abstract: An electrode system for determining an analyte concentration in a human or animal may comprise first and second electrodes. The first electrode may be configured to produce a first signal from which the analyte concentration can be determined, and may have a first measuring sensitivity that is optimized for a first analyte concentration range. The second electrode may be configured to produce a second signal from which the analyte concentration can be determined, and may have a second measuring sensitivity that is optimized for a second analyte concentration range that is different from the first analyte concentration range. An analytical unit may be configured to determine the analyte concentration based on the first signal if the analyte concentration falls within the first analyte concentration range, and to determine the analyte concentration based on the second signal if the analyte concentration falls within the second analyte concentration range.
