Influence of Waterproof Films on the Atomization Behavior of Surface Acoustic Waves

Micromachines, 2019
One of the reasons why commercial application of surface acoustic wave (SAW) atomization is not possible is due to the condensation of aerosol droplets generated during atomization, which drip on the interdigitated transducer (IDT), thereby causing ...
