The hybrid ZnO/Sapphire material is selected to exploit the collective benefits of Zinc Oxide (ZnO) and sapphire for the development of a high performance Surface Acoustic Wave (SAW) device. The microfluidic applications of ZnO/Sapphire layered surface acoustic wave devices are discussed. In addition, acoustic streaming in droplets is investigated using a custom-made ZnO/Sapphire layered device. Experimental results show that a maximum acoustic streaming of ~600 µm/s is achieved when the device is operated at 158 MHz.
