文摘
- •
Design and analysis (experiment and analytical models) of a reusable surface acoustic wave platform for microfluidics.
- •
An analytical model is proposed and verified with experiment, which can be used to design an optimum coupling layer thickness for a frequency to reduce the acoustic attenuation.
- •
A new analytical model, including the generation of higher order lamb waves and its subsequent conversion into the liquid in the channel is developed to predict the acoustic energy transmission at various frequencies.
- •
Novel method for characterizing the SAW energy transmission in fluidic channels.
- •
The analytical models developed in this paper can be used to optimize the power transmission coefficient and hence increase mixing efficiency.
