This is an image captured from a high speed video showing jetting behaviour of a 5uL water droplet induced by ZnO surface acoustic waves (two waves from both sides). The vertical jetting is induced by sub-nanometre amplitudes of surface acoustic waves propagating on a ZnO coated silicon device, interacting with water droplet from both sides. Before the liquid beam breaks up, it forms a shape of crystal snake-like structure.
