Fig. 2 — (A) Schematic view of the subwavelength acoustophoretic voxel ejector (left). The resonance (schematically shown in red) leads to high acoustic pressure amplification while keeping the field strongly confined (right). (B) Side view of the experimental setup (top) and close-up of the tapered nozzle (λ ≈ 14 mm) (bottom). Calculated vertical force distribution inside the subWAVE (C) and its experimental validation (D). (E) Schematic illustration of acoustophoretic printing, which shows that when the total acoustophoretic and gravitational forces exceed the capillary force, droplet detachment and outcoupling from the subWAVE enable patterning on any substrate. (F) Log-log plot of vertical force generated within the subWAVE as a function of drop volume compared to a classical standing-wave levitator.
