초록

The induced voltage on droplets was measured as droplets of DI water and NaCl solution passed through a voltage-applied cylinder. Without an external electric field, ion addition to DI water generated extra induced charge. When NaCl solution was used, the induced voltage of the droplets increased under low humidity but decreased under high humidity compared to that of pure water. A threshold cylinder voltage was required to induce additional charge. At high humidity, application of high voltages to the cylinder led to an asymmetric response of the induced voltage depending on the polarity of the applied voltage.
