Ion Vibration Current/Potential (IVI)is an electric signal that arises when an acoustic wave propagates through a homogeneous fluid. Historically, the IVI is the first known electroacoustic phenomena. It was predicted by Debye in 1933[1]. He pointed out that the difference in the effective mass or friction coefficient between anion and cation would result in different displacement amplitudes in a longitudinal wave. This difference creates an alternating electric potential between various points in sound wave. This effect was extensively used in 1950’s and 1960’s for characterizing ion solvation. These works are mostly associated with names of Zana and Yaeger, who published a review of their studies in 1982[2].
