Technical application of thick film printing technology in CGM dynamic blood glucose meter

CGM dynamic blood glucose monitor is an advanced diabetes management tool, which can monitor the blood glucose changes in the next 7-14 days by implanting micro sensors under the skin. The preparation of its metal electrode often results in deviations in the secondary printing position, such as curling of the substrate after printing and drying, which affects the accuracy of the electrode; The substrate itself has large errors, resulting in frequent alignment failures and other issues.

     CGM dynamic blood glucose monitor is an advanced diabetes management tool, which can monitor the blood glucose changes in the next 7-14 days by implanting micro sensors under the skin. The sensor is the highest and most critical component of the CGM system, consisting of a metal electrode, inner layer, enzyme layer, and outer layer, which directly determines the accuracy of the measurement results of the CGM system. Therefore, the preparation process of the metal electrode is crucial.

      Metal electrodes are printed with conductive lines (silver paste, carbon paste) on PI/PET films with a thickness of 50um to 200um through screen printing, with high printing accuracy requirements. However, this process faces many challenges, and many companies are still in the research and development stage. For example, after printing and drying, the rolled edges of the substrate often cause deviations in the secondary printing position, affecting the accuracy of the electrodes; The substrate itself has large errors, causing common problems such as frequent alignment failures.
      To address these challenges and accelerate the product development process, it is necessary to seek professional printing technology support and solutions. JYUTEC also has rich experience in printing processes such as electrode layers, insulation coatings, enzyme coatings, etc. for traditional blood glucose test strips, and has provided a complete set of printing process technology solutions for multiple enterprises. Taking the electrode printing of a 40 * 150mm CGM dynamic blood glucose monitor as an example, let's take a look at how to solve the above challenges.

Problem 1: After printing and drying, the substrate curled up, causing deviation in the secondary printing position
Solution: Use the jyutec IC-250-LTCC model, which is equipped with a dedicated adsorption platform to firmly fix the substrate on the platform, and use the MARK point alignment method for automatic alignment to minimize the degree of printing position deviation.

Problem 2:The substrate itself has a large error, causing frequent alignment failures and other issues
Solution: Optimize the process sequence between substrate and printing to reduce the impact of substrate errors on printing accuracy.
