Human beings can not artificially construct a dynamic system that operates stably with DC electricity like bacteria. In contrast, it is reported that water droplets in the oil phase to which a certain DC voltage is applied cause smooth reciprocating motion and rotational motion between the needle electrodes. From this, it was difficult to measure the current value flowing through the oil phase containing micro water droplets very small. This time, we succeeded in measuring the current value. We report the change showing the correlation with the reciprocating motion of the micro waterdrop.
