超音波と電界によるマイクロバブルの挙動制御

抄録

The movement of microbubbles charged with a surfactant was controlled by electric fields and ultrasonic wave. The microbubble was placed in water tank in which electrodes and ultrasonic transducers were attached to side and bottom, respectively. First, the microbubbles were moved horizontally by the electric field generated by the electrodes. Next, the ultrasonic vibrator was activated. The moving microbubbles by electric field were aggregated. As a result, small aggregates were not induced by the electric field, but were captured by the ultrasonic wave. The large aggregates were not captured by ultrasonic wave but were guided toward the electrode by the electric field.
