ABSTRACT:
Disclosed is an apparatus and method for ejecting droplets using charge concentration and liquid bridge breakup. The droplet ejection apparatus includes a reservoir storing a liquid; a capillary nozzle having a lower end submerged in the liquid stored in the reservoir and an upper end exposed outside the surface of the liquid, the capillary nozzle transferring the liquid to the upper end using capillary force; a potentiostat for applying a voltage to the liquid; a substrate mount on which a substrate is disposed to face the upper end of the capillary nozzle; and a distance adjusting unit for reciprocatingly moving the substrate between first and second positions with respect to the capillary nozzle, wherein the first position denotes a position where a distance between the upper end of the capillary nozzle and the surface of the substrate is less than a effective distance.
