Abstract

Surface acoustic wave(SAW) nebulization/atomization has been realised on thin ZnOfilm based SAWdevices. The surface acoustic wave nebulization (SAWN) process has been observed to produce significant mist generation and ejected satellitedroplets. By modifying the geometry of the interdigitated transducers to reduce the wavelengths from 400 μm to 120 μm, higher frequency SAWN has been achieved by increasing radio frequency driving frequencies from 11.8 MHz to 37.2 MHz, respectively. Compared with the commonly used LiNbO3 SAWN devices,ZnOfilmdevices exhibit better thermal dissipation, and to date, they have shown no susceptibility to substrate failure during fabrication or operation. They also have the added advantage of the technology being suitable for direct integration with microsystems and integrated circuit microelectronics.
