Embodiment Construction
[0054] Relating to the detailed description and technical contents of the present invention, it is now described as follows with regard to the accompanying drawings:
[0055] see Figure 1 to Figure 3 ,as well as Figure 4A to Figure 4F Shown, the present invention is a kind of preparation method of biosensor test piece, comprises the following steps:
[0056] Step S1: if Figure 4A As shown, a patterned electrode layer 20 is formed on a substrate 10, and the patterned electrode layer 20 has a sensing portion 21 and a reading portion 22 away from the sensing portion 21, wherein the sensing portion 21 and The shape of the reading portion 22 is not particularly limited, and is determined by actual use requirements. In this embodiment, the material of the substrate 10 may be polyethylene terephthalate (PET for short), polypropylene (PP for short), polyimide (PI for short), poly Vinyl chloride (PolyVinyl Chloride, referred to as PVC), etc., and the material of the surface of t...

The invention discloses a substrate structure of a biosensing test piece and a production method of the biosensing test piece. A graphic electrode layer is formed firstly on a substrate and provided with a sensing part; then a blocking-up layer is formed and provided with a main insulation part, a bulging insulation part and a reaction groove which is formed between the main insulation part and the bulging insulation part and corresponds to the sensing part, the main insulation part is provided with two main connecting edges, the bulging insulation part is provided with two auxiliary connecting edges, and the auxiliary connecting edges are entirely connected in partial range of the main connecting edges correspondingly; an enzyme layer is formed in the reaction groove; finally, the main insulation part and the bulging insulation part are separated by cutting. The auxiliary connecting edges are quite short, so that the probability of breaking of the blocking-up layer can be reduced during cutting, the size of the reaction groove is fixed, and the measurement accuracy rate is increased.
Description
technical field [0001] The invention relates to a biological sensing test piece, in particular to a base structure of the biological sensing test piece and a manufacturing method of the biological sensing test piece. Background technique [0002] With the advancement of medical care, chronic diseases have gradually replaced infectious diseases and become one of the main causes of human death. Therefore, the concept of self-health management is becoming more and more popular, but it is time-consuming and laborious to go to the hospital for related tests. Therefore, each family usually configures There are detection instruments for detecting physiological values, such as blood sugar, cholesterol, uric acid, etc., which can be used for quick and simple measurement by means of test strips and reading machines for people to manage their health well. [0003] And the common detection test piece is as " detection test piece, biochemical sensing system, and measuring device " of Chi...
