Abstract

Shear horizontal surface acoustic waves (SH-SAWs) have been regarded as a good candidate for liquid sensing applications, but being inefficient in fluid manipulation due to a minimal fluid coupling between the fluid and acoustic waves. However, in this letter, a vertical jetting function was realized using the SH-SAW generated from a 36°Y-X LiTaO3 SAW device. The jetting of the droplet induced by the SH-SAWs was observed nearly along vertical direction, and the aspect ratio of the liquid beam is proportional to the applied power before breaking up, which is dramatically different from those generated from the conventional Rayleigh SAWs. By conducting theoretical simulation and experimental investigation on the SH-SAWs systematically, we concluded that the wave/energy pressure dissipated into the sessile droplets causes this vertical ejection on the device surface.
