In this study, we developed a micropyramid array electrode that facilitates contact between a nitrocellulose membrane and electrode, which is important to realize a quantitative and sensitive electrochemical detection system for immunochromatography. We evaluated the micropyamid array electrode with our newly developed detection system that can measure contact forces between a membrane and electrode, and also investigated the relationship between redox current and contact forces. By using normal pulse voltammetry, we observed higher reduction currents over a flat surface electrode at lower contact forces with the micropyramid array.
