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.
