Comparing with evaporation, sputtering and other methods, electrodeposition is much cheaper and more convenient in the field of fabricating thin film electrodes, which are versatile to various sensor platforms. In this work, a three-microelectrode system electrodeposited on printed circuit boards was developed, by which the electrode could be directly connected to external detection circuits. The electrodeposited three-electrode system consisted of a gold electrode (working electrode), a platinum electrode (counter electrode) and a Ag/AgCl electrode (reference electrode). The size of a single electrode was 0.5 mm × 0.7 mm, by which the amount of sample required for a single test was only 10-20 μL. When connected to external circuits, the three-microelectrode system could conduct a rapid, quantitative and nonenzymatic detection of glucose in artificial sweat (pH 4.7) by multipotential step and chronoamperometry with a linear range of 50-500 μmol/L and a detection limit of 20 μmol/L.
