Abstract
The present invention relates to an apparatus for controlling droplet motion in an electric field by reducing volume of a single droplet to a very small volume using a strong electric field and controlling a position of a droplet using a repulsive force of the same polarity, and a method of the same. The apparatus according to an exemplary embodiment of the present invention includes a first electrode, an insulator disposed above the first electrode, a discharge tip disposed above the insulator by a predetermined distance and dividing a transferred fluid into a small volume of a droplet, and a second electrode contacting the fluid supplied through the discharge tip. The first electrode and the second electrode may form an electric field at an end of the discharge tip by forming a potential difference between the first electrode and the second electrode.
