Droplet Transport by Surface Acoustic Waves

Acoustic droplet ejection Acoustic levitation of droplets Acoustic particle concentration Drop on demand Droplet manipulation Droplet transport by surface acoustic waves Radiation pressure Surface acoustic waves... 

In this section, the equations governing acoustic waves in fluids and surface waves in solids are described and concepts from nonlinear acoustics such as radiation pressure and acoustic streaming are reviewed in order to provide an appropriate framework for modeling and simulation of droplet transport by acoustics. 

We now apply the fundamental concepts outlined above to three specific examples that are relevant to the topic of droplet transport by acoustics namely, acoustic droplet ejection, droplet transport almig a solid surface using surface acoustic waves, and acoustic levitation of droplets. 

Transport of droplets by acoustics refers to the use of acoustic or ultrasonic waves in fluids or on solid surfaces to generate, manipulate, positimi, or transport liquid droplets, ranging from picoliters to microliters in volume, surrounded by a gas or immiscible liquid phase and/or attached to a solid surface.
