Abstract
Provided are a droplet emitting apparatus and a method of emitting droplets using the same. The apparatus includes a solution tank for containing a solution; a nozzle including an opening through which at least a droplet of the solution is emitted; and a voltage generator including a piezoelectric material for generating a voltage by instantaneous pressure application, wherein the voltage generated by the pressure to the piezoelectric material is applied to the solution in order for the at least a droplet of the solution to be emitted through the nozzle.
