Abstract:
A method of manufacturing a electrode test strip, comprising the steps of:offering an insulating base plate; printing a layer of conductive films to be a cathode and an anode, e cathode and the anode are isolated; forming a first spacer and a second spacer on the conductive films to expose two ends of the cathode and the anode, wherein a channel trench is formed between the first and the second spacer; spreading a reagent solution on a bottom surface of the channel trench; drying the reagent solution to form a reactive film in the channel trench; and forming a cover with a first opening on the spacer, wherein the first opening is located on the channel trench and two second openings are surrounded by the insulating base plate, the first spacer, the second spacer and the cover.
