Technical application of high-precision thick film screen printing technology in CGM dynamic blood glucose monitor

The CGM dynamic glucose monitor is an advanced diabetes management tool that monitors blood glucose changes in the next 7 to 14 days by implanting tiny sensors under the skin. The sensor is the highest barrier and core component of the CGM system. It is composed of a metal electrode, an inner layer, an enzyme layer and an outer membrane. It directly determines the accuracy of the measurement results of the CGM system, so the preparation process of the metal electrode is very critical.

The metal electrode is printed with conductor lines (silver paste, carbon paste) on a PI/PET film with a thickness of 50um to 200um through screen printing, and the printing accuracy is required to be high. However, this process faces many challenges, and some companies are still struggling on the research and development road. For example, the base material curls after printing and drying, which often leads to deviations in the secondary printing position, affecting the accuracy of the electrode; the base material itself has large errors, causing frequent alignment failures and other problems.

In order to solve these challenges and speed up the product development process, it is necessary to seek professional technical support and solutions. He has rich industry experience in CGM dynamic glucose monitor electrode printing and has provided a full set of printing process technology solutions for many companies. At the same time, Oulette also has extensive experience in printing processes such as electrode layers, insulating coatings, and enzyme coatings for traditional blood glucose test strips. Let’s take the 40*150mm CGM dynamic glucose monitor electrode printing as an example to see how to solve the above challenges.
01 The base material curls after printing and drying, causing deviation in the secondary printing position.
The machine is equipped with a special adsorption platform to firmly fix the substrate on the platform, and uses the MARK point alignment method for automatic alignment to minimize the printing position deviation.
02 The base material itself has large errors, causing problems such as frequent alignment failures.
Optimize the process sequence between the substrate and printing to reduce the impact of errors in the substrate itself on printing accuracy.
With the continuous development of technology, CGM dynamic blood glucose monitors will provide more and more diabetic patients with more reliable and convenient health management tools, and the market prospects will also be broader. Ouellette will continue to delve deeply into the field of thick film printing, continue to carry out technological innovation and process optimization and upgrading, actively expand the product line of high-precision thick film printing equipment, provide thick film printing solutions to more industry customers, and jointly promote the vigorous development of related industries.
