Importance of technology for measuring ion distribution in biological and fluidic environments is increasing. In this study, we proposed and verified a multi-chip ion imaging device using signal transmission between multiple sensor chips connected in series, and successfully obtained sensor responses due to K+ concentration diffusion in an experimental system with three sensor chips connected at 1.5 cm intervals. The sensor response due to K+ concentration diffusion was successfully obtained in an experimental system consisted of three sensor chips demonstrating real-time measurement of ion distributions on wide areas as an image.
