Self-Aligned Interdigitated Transducers for Acoustofluidics [PDF]
Micromachines, 2016 Surface acoustic wave (SAW) is effective for the manipulation of fluids and particles in microscale. The current approach of integrating interdigitated transducers (IDTs) for SAW generation into microfluidic channels involves complex and laborious microfabrication steps.
