Benefits of technology

[0010]Embodiments of the invention disclosed herein include electrochemical analyte sensors comprising elements such as electrodes and/or electrode combinations (e.g. working and counter electrode combinations) designed to optimize factors including the reactivity, sensitivity, functioning and lifespan of the analyte sensors. An illustrative embodiment of the invention is a method of performing an electrochemical reaction within an analyte sensor comprising using an analyte sensor constructed to include an electrode layer configuration that is designed to optimize the electrochemical reaction at the electrode when the electrode is exposed to an analyte. In such methods the analyte sensor typically includes at least one electrode disposed upon a base substrate where this base substrate comprises a geometric feature selected to increase the surface area of an electrochemically reactive surface o
