Problems solved by technology
The two above-mentioned patents all show the use of a metal surface or a printed conductive material surface as an electrode area 165, 166, 171, 172 for an electrochemical reaction, because the electrode area is located on the metal strip or conductive material surface, and the area of the electrode area is usually larger than the cross-section of the metal strip or the conductive substance itself, so performing the sample measurement of the fluid sample on this electrode area will inevitably lead to the demand for the finished product of the test piece. Fluid sample volume is large, so it is not ideal
[0004] Therefore, how to improve the problem that the volume of the fluid sample required by the disposable electrochemical sensory test piece is too large, after the inventor's experiments, tests and researches, finally obtained a disposable electrochemical sensory test piece with a small electrode area and Its manufacturing method, in addition to effectively solving the previous shortcomings of excessive fluid sample volume requirements, can also improve the convenience of simplifying the manufacturing process of electrochemical detection test strips and minimal sample volume
