Electrochemical sensing test piece, its manufacturing method and its electrode layer manufacturing method

Abstract

An electrochemical sensing test sheet, its manufacturing method and its electrode layer manufacturing method, the electrochemical sensing test sheet manufacturing method comprises the following steps: forming a plurality of spaced through holes respectively penetrating through the substrate on an insulating substrate; An active metal layer is formed at least inside each through hole of the substrate; an electrode layer made of metal material is formed on each active metal layer; an electrochemical electrode electrically connected to the electrode layer is formed on the upper surface of the substrate. a reaction layer; and correspondingly cover a covering member on the electrochemical reaction layer. Using the active metal layer to combine the electrode layer in the through hole of the substrate can not only provide a simpler manufacturing process and better bonding between the electrode and the substrate, but also reduce the cost of metal electrode raw materials.

Description

technical field [0001] The invention relates to a sensory test piece and a manufacturing method thereof, in particular to an electrochemical sensory test piece which is easy to process and can reduce the cost of metal electrode raw materials and a manufacturing method thereof. Background technique [0002] refer to figure 1 , is an existing electrochemical test strip 8, which is suitable for testing the content of an analyte in a fluid to be measured, such as the blood sugar content in blood or the concentration of heavy metals in sewage, etc. The electrochemical test strip 8 includes an insulating substrate 81 . A metal conductive layer 82 printed on the insulating substrate 81 , a corresponding insulating layer 83 covering the insulating substrate 81 , a reagent reaction layer 84 corresponding to the metal conductive layer 82 , and a cover plate 85 . Although the electrochemical test strip 8 can achieve the purpose of detecting the content of the analyte, since the metal ...

AI Technical Summary

Problems solved by technology

Although the electrochemical test strip 9 can also achieve the purpose of detecting the content of the analyte, and compared with the above-mentioned electrochemical test strip 8, the consumption of metal electrode raw materials during manufacture is less, but because the electrodes 92 and the insulating substrate 91 are made separately Molding, then installation and combination, the production process is relatively cumbersome, and the size of the electrode 92 and the corresponding through hole 912 must be accurate enough to achieve a good degree of bonding
