1. A control-engaged electrode-driving method for droplet actuation, comprising:
providing a first voltage to a first electrode for kicking off a droplet;
naturally discharging from a second voltage to a third voltage for maintaining a droplet movement;
providing a fourth voltage to the first electrode for accelerating the droplet;
repeating naturally discharging from the second voltage to the third voltage and providing the fourth voltage to the first electrode;
providing the first voltage to a second electrode when a centroid of the droplet reaching a centroid of the first electrode; and
repeating naturally discharging from the second voltage to the third voltage and providing the fourth voltage to the second electrode.
