Abstract: The effects of potential stabilization time, electric field response performance, conductivity and water flow fluctuations of Ag/AgCl and carbon fiber marine electric electrodes on electrode response were investigated. The results show that the potential stabilization time of the carbon fiber electrode is short, which can better resist the fluctuation of water flow, but the response gain to low frequency signals is small; The Ag/AgCl electrode has a longer stabilization time than the carbon fiber electrode, and has a larger response gain to low frequency signals, but has poor resistance to fluctuations in water flow.
