Abstract: The present invention provides an electrochemical sensor that employs multiple electrode areas that are exposed for contact with a body fluid, e.g., when the sensor is inserted subcutaneously into a patient's skin. The exposed electrode areas are arranged symmetrically, such that a symmetrical potential distribution is produced when an AC signal is applied to the sensor. The sensors in accordance with these teachings can advantageously be used with AC signals to determine characteristics of the sensor and thus improve sensor performance. These teachings also provide a biocompatible sensor with multiple reference electrode areas that are exposed for contact with body fluid.

Abstract: Disclosed herein are portable diagnostic measurement devices for determining at least one analysis parameter of a bodily fluid, in particular for determining an analyte concentration in a bodily fluid as can occur in blood glucose determinations. Also disclosed are analysis systems including the measurement device and at least one disposable test element. The test element can be designed as a carrier strip and can contact a receiving surface of the measurement device at least partially in a flat manner, where the receiving surface is arranged on a narrow side of the housing of the measurement device.

Abstract: An electrode system is disclosed for measuring a concentration or presence of an analyte under in-vivo conditions, where the electrode system includes at least one electrode with immobilized enzyme molecules and an improved diffusion barrier that controls diffusion of the analyte from body fluid surrounding the electrode system to the enzyme molecules. The diffusion barrier includes a hydrophilic polyurethane or a block copolymer having at least one hydrophilic block and at least one hydrophobic block. The electrode system also can include a spacer membrane that includes a hydrophilic copolymer of acrylic and/or methacrylic monomers.
