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