Embodiment 1

[0034] Such as figure 2 and Figure 4 As shown, this embodiment provides a double-sided screen-printed electrode based on a flexible plastic substrate, including a substrate 4 , a working electrode 1 and a counter electrode 3 . A working electrode is printed on one side of the substrate, and a counter electrode is printed on the other side. The working electrode 1 and the counter electrode 3 are respectively located at the same position on the front and back sides of the substrate 4, and the vertical projections of the working electrode 1 and the counter electrode 3 on the center plane of the substrate 4 coincide, that is to say, the working electrode 1 and the counter electrode 3 The position, shape and size are all the same, and the mirror surface is symmetrical with the substrate 4. In addition, the working electrode 1 and the counter electrode 3 are not connected to each other and are independent electrodes.

[0035] The substrate can be selected from a wide range of m...

Abstract

The present invention discloses a double-sided silk-screen printing electrode based on a flexible plastic substrate and a preparation method of the double-sided silk-screen printing electrode. The preparation method comprises the following steps: S1, cutting the substrate made of a flexible plastic material to a size facilitating printing, then cleaning surface impurities with absolute ethyl alcohol and deionized water in sequence, and then conducting drying; S2, printing a working electrode on one side of the substrate and conducting drying after the printing is finished; S3, printing a counter electrode at a same position of the other side of the substrate and conducting drying after the printing is finished to obtain a double-sided silk-screen printing electrode precursor; wherein the working electrode and the counter electrode are not conducted with each other; and S4, integrally cutting the substrate, the working electrode and the counter electrode in the double-sided silk-screenprinting electrode precursor into specified shapes and sizes to obtain the double-sided silk-screen printing electrode. The substrate made of the flexible plastic material is used, so that the electrode has flexible and bendable characteristics, and discomfort can be reduced after the electrode is implanted into a living body. Besides, the working electrode and the counter electrode are separatelyprinted on the two sides of the substrate, so that a structure of the electrode is optimized and the size is reduced.

Description

technical field [0001] The invention belongs to the field of implantable sensors, in particular to a double-sided screen printing electrode based on a flexible plastic substrate and a method thereof. Background technique [0002] Implantable sensors have great advantages in real-time measurement of physiological and biochemical parameters in the human body. By implanting sensor electrodes into specific parts of the human body and applying voltage or current through external devices, real-time monitoring of certain physiological and biochemical parameters in the human body can be realized. At the same time, the accuracy is higher and the response is more sensitive. [0003] For example, with the gradual increase of diabetic patients in recent years, people are paying more and more attention to diabetes. During the treatment of diabetes, monitoring changes in blood glucose levels is a very important and effective treatment. The traditional blood glucose meter conducts daily ...
