摘要：

This paper presents the electric field-based on-demand size controllable droplet generation, falling direction manipulation, and repulsion. We controlled the size of the generated gallium-based liquid metal droplets by adjusting the amplitude of the applied electric field. The volume and the number of the generated liquid metal droplet depending on flow rate and applied voltage were measured. We also studied time-dependent falling velocity of the generated liquid metal droplet according to various applied voltages. In addition, by changing the electric field which was achieved by controlling the position of the circular-shaped electrode, the falling direction of liquid metal droplet can be manipulated. Finally, the electro-hydrodynamic repulsion of the liquid metal was demonstrated.
