The noncontact ultrasonic mixing of two droplets is demonstrated, for the first time, by controlling the acoustic field using the following two methods: (1) by changing the distance between the vibrator and the reflector and (2) by modulating the driving voltage amplitude applied to the vibrator. The operating principle is confirmed by measuring the acoustic pressure distribution and the temporal change in the acoustic pressure near the mixing position. We also show that the stable mixing of droplets with high repeatability is feasible by method (2), which does not involve the use of mechanically moving parts.
