✦ Synopsis
By applying constant electric current, self-sustained oscillations of electric potential were observed across a membrane filter impregnated with triolein (glycerol trioleate) placed between KCI and NaCl aqueous solutions. The stability of the oscillations was much improved compared to those of previous workers. Besides, by applying constant electric current, the oscillations across this type of membrane became reproducible and always easily controllable for the first time. Analyzing the data obtained, it was shown that the oscillation period was controlled by the base electric potential. It is suggested that the generation of the oscillation may be explained as repetitions of dielectric breakdown and restoration of a part of the membrane.
