Abstract

In this study, silver paste was made with and without M13(sol) particles, and then electrodes were printed using screen printing. The conductivity changes and electro-mechanical properties of the printed electrodes were studied using the stretching test, bending test, and bending figure test. For silver pastes with M13(sol) particles, the resistance was measured up to 140% with increased strain. In contrast, the bending test and bending figure test showed no change in resistance regardless of the presence of M13(sol) particles. The scanning electron microscope was used to observe the particle difference, and indicated that holes generated by the sintered flakes were connected by non-sintered M13(sol) particles at 130 °C for improved flexibility.
