| Outline of Final Research Achievements |
To avoid contamination and increase processing speed, a non-contact technology for manipulating droplets will be required in production process of chemical materials and development of new materials. In this study, we proposed and developed systems for various kinds of processing such as transport, mixing, dispensing, and analysis of liquid sample without contact.
For non-contact mixing of two drops of different liquid, we proposed to utilize two orthogonal ultrasonic standing wave fields. The method was proved with the experiments at several 10 kHz. To eject single droplet from a container, the conditions of the intensity and time duration of 1-MHz burst focused waves were examined. We demonstrated a coating process for a small object levitated at the nodal point of ultrasonic standing waves. A vibration system stabilized with a feedback oscillator was developed for the coating processing.
