Technical application of high-precision thick film screen printing technology in dynamic blood glucose monitor Dynamic blood glucose monitor is an advanced diabetes management tool that monitors blood glucose changes over the next 7 to 14 days by implanting micro sensors under the skin. Its sensor is the most core component with the highest barriers in the system. It consists of metal electrodes, inner layer, enzyme layer and outer membrane, which directly determines the accuracy of the system measurement results. Therefore, the preparation process of its metal electrode is very critical. The metal electrodes are printed with conductor lines (silver paste, carbon paste) on PI/PET films with a thickness of 50 um to 200 um by screen printing, and the printing accuracy is high. However, this process faces many challenges, and some companies are still struggling to move forward on the R&D road. For example, after printing and drying, the edges of the substrate often lead to deviations in the secondary printing position, affecting the accuracy of the electrode; the substrate itself has large errors, resulting in frequent failure of alignment. In order to solve these challenges and accelerate the product development process, we need to seek professional technical support and solutions.
