Abstract

Effects of the hydrostatic pressure difference across the oil to water interface on a self-excited potential oscillation at a micropore have been investigated by potential measurement and microscopic observation. The amplitude and frequency of the oscillation are precisely controlled by means of changing the hydrostatic pressure. This effect of hydrostatic pressure is due to the change in the diameter of a dome that is built at the micropore. These results are qualitatively consistent with our previous ones [Jpn. J. Appl. Phys. 30 (1991) L1435]; i.e., the self-excited potential oscillation can be controlled through changes in the shape or the size of the interface.
