Abstract (en)

[origin: WO9913099A1] An improved electrochemical sensor strip is disclosed. In a multiple electrode sensor strip, equalization of electrode nonworking areas, as well as working areas, enhances the overall precision and accuracy of the measurements made using the sensor strip. The beneficial effect of area equalization is most pronounced at relatively low glucose concentrations. In the present invention, the exactness and reproducibility of electrode area equalization is improved by avoidance of overlap between the electrodes and a dielectric coating that defines an electrode exposure area.
