In this study, a device using an ultrasonic vibration and a microchannel has been developed to obtain emulsions. The process of generating emulsions involves a Y-type microchannel and an ultrasonic device. Once micron-sized emulsions were generated by the Y-type microchannel, the micron-sized emulsions were sonicated using ultrasonic vibration to produce emulsions. Although the diameter of emulsions was 30 mm using the Y-type microchannel, the diameter of the sonicated emulsions was about 200 nm. In addition, as the applied voltage was increased, sonicated emulsions became smaller and the distribution became sharper.
