Abstract
This paper presents a novel device which can atomize a droplet into narrow mist spray using surface acoustic wave (SAW). A channel was cut into piezoelectric substrate between two IDT electrodes which drives SAWs in opposing directions. Then, SAW streaming in opposing directions are isolated in both sides of the channel, which converged atomized mist into narrow mist spray, whose width is nearly 1/4 compared with that of no-channel device.
