    "abstract": "The effect of a stationary electric field on a water droplet with a diameter\nof several tens micrometers in oil was examined. Such a droplet exhibits\nrepetitive translational motion between the electrodes in a spontaneous manner.\nThe state diagram of this oscillatory motion was deduced; at 0-20 V the droplet\nis fixed at the surface of the electrode, at 20-70 V the droplet exhibits\nsmall-amplitude oscillatory motion between the electrodes, and at 70-100 V the\ndroplet shows large-amplitude periodic motion between the electrodes. The\nobserved rhythmic motion is explained in a semi-quantitative manner by using\ndifferential equations, which includes the effect of charging the droplet under\nan electric field. We also found that twin droplets exhibit synchronized\nrhythmic motion between the electrodes.",
