Actuation of sessile droplets using surface acoustic wave

In recent years, the high intensity surface acoustic wave (SAW) generated by interdigital transducers (IDT) patterned on surfaces the of a piezoelectric substrate had been reported for many applications in chemical and biological processes. One of the major research areas is the research on the effe...
