  • Droplet ejection apparatus and droplet ejection method using the same
    Patent number: 12023923
    Abstract: In a droplet ejection apparatus and a droplet ejection method using the droplet ejection apparatus, the droplet ejection apparatus includes a liquid supply unit, a nozzle and a standing wave generating unit. The liquid supply unit is configured to provide a pressure to a liquid. The nozzle is connected to the liquid supply unit through a connecting conduit, to eject the liquid with a droplet. The standing wave generating unit is configured to generate a standing wave around the nozzle at which the droplet is formed, to detach the droplet from the nozzle.
