Description

This paper presents droplet transportation and droplet generation experiments using EWOD (Electro wetting on dielectric). EWOD is a technology for manipulating droplets discretely by controlling the electrical wettability of surface.1.5 μL ~5 μL of pure water droplets were successfully transported using transport device with an electrode size of 1.5 [mm] x 0.3 [mm]. During the generation experiments, droplet size varied from 2.5 μL to 4 μL were easier to generate. And it is verified that the minimum voltage of generation is 70V. By changing the program and the shape of the electrode, it is expected that a successful droplet generation can be achieved.
