N2 - In this paper, an F-P interferometer optoelectrode structure functionalized by conductive indium tin oxide (ITO) thin film is first proposed. When the F-P cavity is filled with electrolyte, the effective refractive index in the cavity can be modulated by applying an electrical potential to form an electric double layer on the interface of the electrolyte and electrode. Significantly, this work presents a novel structure of integrated F-P interferometer optoelectrode functionalized by conductive ITO to measure the conductivity of the electrolyte. And it is the first time to use interference spectrum to react the conductivity of solution, which provides a new method for conductivity detection. This simple preparation, convenient operation, and low-costed optical fiber F-P interference optoelectrode has great potential in the biochemical analysis, biosensing, electrochemical analysis and battery electrode surface monitoring.
