  • ELECTRODE ARRANGEMENTS FOR BIOSENSORS
    Publication number: 20110186428
    Abstract: The present invention relates to a biosensor. The biosensor includes a support substrate, electrodes positioned on the support substrate, a spacer substrate positioned on the support substrate, and a cover positioned on the spacer substrate. The cover cooperates with the support substrate to define a capillary channel. The electrodes include at least one working electrode defining a working electrode area in the capillary channel. The working electrode is configured to minimize variation in the working electrode area in the capillary channel due to variations in the spacer substrate placement relative to the working electrode.
