1. A method of determining an analyte concentration of a fluid, the method comprising the acts of:
- providing an electrochemical sensor system including;
a substrate having porosity including at least one aperture extending through the substrate,an enzyme coupled to the substrate, the enzyme being configured to chemically react with the analyte in the fluid,at least one conductive electrode coupled to the substrate, each electrode of the at least one electrode having a first surface and a second surface on the opposite side of the first surface, anda hydrogel having a first layer and a second layer, the hydrogel extending through the at least one aperture and contacting the first surface and the second surface of the at least one electrode and the substrate, the hydrogel being configured to carry the analyte of the fluid into contact with both the first surface and the second surface of the at least one electrode, with the at least one electrode and the substrate being sandwiched between the first layer and the second layer of the hydrogel;
placing the electrochemical sensor system on the skin; and
determining the analyte concentration of the fluid.

Abstract
An electrochemical sensor system is adapted to assist in determining an analyte concentration of a fluid. The electrochemical sensor system comprises a substrate, conductive material and a hydrogel or liquid. The substrate having porosity therethrough. The conductive material includes at least one electrode. The at least one electrode is coupled to the substrate. The at least one electrode has a first surface and an opposing second surface. The hydrogel or liquid is adapted to assist in carrying the analyte of the fluid to the first and second surfaces of the at least one electrode.
