Tuning the distance between two beads. This movie corresponds to the data presented in Fig. S4. Here, the distance between two beads (10-μm-diameter polystyrene beads) within an acoustic well was regulated by applying a pulsed RF input signal (0.5-s duration and 2-s interval) to the perpendicular IDT pair. The movie is in real time.
