Abstract:
In a droplet ejection apparatus and a droplet ejection method using same, the droplet ejection apparatus comprises a solution supply unit, a nozzle, and a standing wave-generating unit. The solution supply unit provides a pressing force to a solution. The nozzle is connected to the solution supply unit via a connection tube and ejects the solution in the form of droplets. The standing wave-generating unit forms standing waves in a region around the nozzle where droplets are formed, thereby separating droplets from the nozzle.
