Design of interdigitated transducers for acoustofluidic applications

Nanotechnology and Precision Engineering, 2022
Interdigitated transducers (IDTs) were originally designed as delay lines for radars. Half a century later, they have found new life as actuators for microfluidic systems. By generating strong acoustic fields, they trigger nonlinear effects that enable pumping and mixing of fluids, and moving particles without contact.
