Ion Vibration Current
Historically, the IVI is the first known electroacoustic effect. It was predicted by Debye in 1933. 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 1960s for characterizing ion solvation. These works are mostly associated with names of Zana and Yaeger, who published a review of their studies in 1982.

Famous quotes containing the words vibration and/or current:
“In the very midst of the crowd about this wreck, there were men with carts busily collecting the seaweed which the storm had cast up, and conveying it beyond the reach of the tide, though they were often obliged to separate fragments of clothing from it, and they might at any moment have found a human body under it. Drown who might, they did not forget that this weed was a valuable manure. This shipwreck had not produced a visible vibration in the fabric of society.”
—Henry David Thoreau (1817–1862)
“Our current obsession with creativity is the result of our continued striving for immortality in an era when most people no longer believe in an after-life.”
—Arianna Stassinopoulos (b. 1950)
