| Research Abstract |
For the application in pharmaceutical and high-quality chemical industries, totally non-contact transport of droplet is highly demanded. Techniques for non-contact mixing and dispensing are also required. We have succeeded in the noncontact linear transport of ethanol droplets of 1.5 mm in diameter using a semi cylindrical acoustic waveguide. The waveguide was composed of a bending vibration plate and a semi cylindrical reflector, and a traveling wave acoustic field was excited in the waveguide. The droplet was levitated due to the radiation force of the acoustic field, and then, pushed in horizontal direction because of acoustic streaming. The transportation distance was 65mm and the terminal velocity was over 2 m/s.
We also succeed in noncontact mixing of two droplets, and dispensing a droplet through a hole installed in the reflector plate.
