Abstract The Ag/AgCl electrode has been widely used in biomedical electrodes due to its many advantages. In recent years, Ag/AgCl electrode materials prepared by screen printing method have attracted extensive research interest, but the effect of Ag/AgCl paste on the performance of screen-printed flexible Ag/AgCl electrodes has been neglected. In this paper, the effects of different types and contents of silver powder on the conductivity and microstructure of Ag/AgCl paste electrode were studied, to optimize the best type of silver powder and the ratio of Ag: AgCl for paste preparation. The structure of the Ag/AgCl electrode was designed, and the performance of the fabricated Ag/AgCl electrode was evaluated using an electrochemical workstation, an impedance tester, and an electrocardiogram detection system. When flaky silver powder H with high specific surface area is used and the ratio of Ag:AgCl is 5:5, the prepared electrode can meet the requirements of electrocardiogram testing.
