Microfluidic heater assisted by Rayleigh Surface Acoustic Wave on AlN/128°Y-X LiNbO 3 multilayer structure

TL;DR: In this paper, a multilayer structure is reported which consists to bury the Inter-digital Transducers (IdT) under a sputtered Aluminium Nitride (AlN) layer to electrically insulate Thus, microdroplets can be deposited directly on the IdT, which improves the efficiency of the device Indeed, effect of AlN layer on 128°Y-X cut lithium niobate (LiNbO3) substrate is studied based on simulations, they show that electromechanical coupling coefficient can be enhanced with alN layer leading to a better heating of
