Abstract

A liquid actuator is realized using a surface acoustic wave (SAW) device. A longitudinal wave is radiated into a liquid when the liquid is placed on a surface acoustic wave (SAW) propagating surface. Nonlinear phenomena are caused by a radiated longitudinal wave and are called SAW streaming. Several applications of liquid actuators using SAW streaming are reported. Atomization is one of them. In this paper, mechanism of the atomization is discussed. First, an elliptical displacement at water/128YX-LiNbO₃ interface was calculated using Campbell and Jones method. Then, mechanism of the atomization is discussed using observation results. Finally, for practical application, long time atomization is examined.
