Abstract:
Provided is a droplet dispensing device having a nonconductive capillary nozzle. The droplet dispensing device comprises: a nonconductive capillary nozzle disposed in a downward position; a pump connected with the nonconductive capillary nozzle through a hermetically sealed fluid tube and generating a negative pressure to decrease the influence of gravity on a solution within the nonconductive capillary nozzle and the fluid tube; and an open circuit voltage supplier applying a voltage to the solution. The droplet dispensing device supplies the solution by capillary force to regularly maintain the shape of a droplet surface in the tip of the nonconductive capillary nozzle without using a separate driving device.
