Abstract

Microvolcano like surface acoustic wave (SAW)
nebulization/ atomization has been realised on ZnO film
based SAW devices. The SAW nebulization (SAWN)
process has been observed to produce significant mist
generation and ejected satellite droplets. By modifying the
geometry of the interdigitated transducers to reduce the
wavelengths from 400 μm to 64 μm, higher frequency SAW
nebulization has been achieved by increasing radio frequency
(RF) driving frequencies from 11.8 MHz to 64 MHz
respectively.
