Electric charge concentration type droplet dispensing device having nonconductive capillary nozzle

A droplet dispensing device comprising:

• a solution reservoir;
• at least one nonconductive capillary nozzle disposed in a downward direction with respect to the solution reservoir;
• a pump connected the solution reservoir 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 solution reservoir;
• a Second electrode immersed in the solution;
• the second electrode applying a voltage to the solution;
• and
• a first electrode disposed outside the fluid tube and connected with an open circuit voltage supplier to generate an induced electric force to the second electrode.
