| Research Abstract |
To mix two kind of water droplet with a few tens micro L by resonant vibration of a water droplet under AC electric field, behavior of a viscous water droplets placed on a super-hydrophobic material was investigated. Extension ratio of the water droplet under AC electric field for relation of frequency were investigated from observation of the variation of the droplet shape for ac voltage from 5 to 20 Hz applied to a pair of parallel electrodes where a water droplets of 100 micro L was placed. A 50-micro-L viscous water droplet containing fluorescent material and water droplet made to be coalesced to confirm liquid flow inside of the droplet. The mixing performance of viscous droplets was increased by using three dimensional electric field.
