Abstract
An apparatus for merging and mixing two droplets using electrostatic forces includes a substrate on which are disposed a first originating electrode, a center electrode, and a second originating electrode. The electrodes are disposed such that a first gap is formed between the first originating electrode and the center electrode and a second gap is formed between the second originating electrode and the center electrode. A dielectric material surrounds the electrodes on the substrate. A first droplet is deposited asymmetrically across the first gap, and a second droplet is deposited asymmetrically across the second gap. Voltage potentials are placed across the first gap and second gap, respectively, whereby each droplet is moved toward the other such that they collide together, causing the droplets to merge and mix, and causing oscillations within the collided droplet.
