The biochemical sensing device has the advantages of simple operation, small volume, and fast detection speed. Figure 1 shows a schematic view of the appearance of a conventional biochemical test piece. Figure 2 shows an exploded view of the biochemical test strip of Figure 1. As shown in Figs. 1 and 2, the biochemical sensing test piece 100 is a blood glucose test piece including an electrode substrate u, a flow path plate 120, and a top plate 130. The electrode substrate 11 is formed by printing a plurality of electrodes and circuits on a substrate by a printing technique. The flow passage plate 120 defines a notch 122 which is formed by penetrating the upper surface above the flow passage plate 120. In order to allow the blood to flow more smoothly, an opening 135 may be provided at the position of the opening 122 of the corresponding flow path plate 12 of the top plate 130. When the biochemical test piece is manufactured, the electrode substrate 11A, the flow path 201219779 plate 120, and the top plate 130 need to be bonded together. The flow path plate 12 is placed between the electrode substrate 110 and the top plate 130, and the electrode substrate 11A, the flow path plate 12A, and the top plate 130 collectively define a first-class track 15〇.

In order to make the above and other objects, features and advantages of the present invention more compelling, the following is a detailed description of the ship's cooperation. [Embodiment] Fig. 3 is a flow chart showing a method of manufacturing a biochemical test piece according to an embodiment of the present invention. 4A to 4D are views showing the steps of a method of manufacturing a biochemical test piece according to an embodiment of the present invention. As shown in Fig. 3 and Figs. 4 to 4D, a method of manufacturing a biosensing test piece according to an embodiment of the present invention comprises the following steps. As shown in FIG. 4A, step S02: forming a substrate 210, and the substrate 210 defines at least one groove 211. In one embodiment, the thermoplastic plastic can be injection molded into a substrate 210 defining at least one recess 211 by injection molding techniques. Preferably, the substrate 210 is a 201219779 body. The groove 211 extends downward from the upper surface of the substrate 21A and does not pass through to the lower surface of the substrate 210, that is, the bottom surface of the groove 211 is defined by the lower half of the substrate. As shown in Fig. 4B, (d) Simplified: laser processing is performed on the substrate 212 to which the electrode is to be formed, wherein the region 212 where the electrode is to be formed extends from the recess 2U_ to the upper surface of the substrate 21A. In one embodiment, the surface of the region 212 where the electrode is to be formed is roughened by laser, more specifically, the surface of the region 212 is formed into a porous structure (p〇r〇us). In one embodiment, according to the laser activation technique, a special chemical agent is added and the region 212 where the electrode is to be formed is activated by laser, so that the surface of the region 212 is subjected to a physicochemical reaction to form a metal core, preferably, except In addition to the laser activation treatment of the region 212, the surface of the region 212 is roughened at the same time. As shown in Fig. 4C, step S06: an electrode structure 220 is formed on a region 212 of the substrate 210 where the electrode is to be formed, wherein the electrode structure 22 extends from the inside of the recess 211 to the upper surface of the substrate 210. In one embodiment, the electrode structure 220 is applied to the region 212 to be formed by the coating technique. Since the surface of the region 212 has been roughened, the electrode structure 220 can be fixed on the region 212 of the substrate 21〇.

Thus, only the electrode structure 220 is formed on the region 212 where the electrode is to be formed on one of the substrates 21 . Furthermore, since the aforementioned region 212 where the electrode is to be formed has been roughened and formed with a porous structure, the electrode structure 220 can be fixed (or anchored) to the region 212 of the substrate 210. Further, the type of the metal layer is not limited in the present invention, and it may be, for example, gold, nickel, silver or copper. According to the consistent embodiment of the present invention, the electrode structure 220 can be formed on the surface having the groove by using the laser activation technology and the electro-recording technology; and the electrode structure 220 having a line width of 5 to 8 μm can be manufactured. With the conventional printing technology, the size of the biochemical test piece can be further reduced. As shown in FIG. 4C and FIG. 4D, step s〇8: the test chemical is applied to the end of the electrode structure 22〇 at the end of the recess 211, and covers a top plate 23〇, thereby defining the substrate 210 and the top plate 23〇. At least the first-class track, the position of the at least one grab track corresponds to at least the position of the groove 211.
