| Outline of Final Research Achievements |
Micromechcnisms often stop due to the adhesion between parts. The one of forces that cause the adhesion in micromechcnism is the Casimir force, which is generated by the vacuum fluctuations. The Casimir force usually is attractive. However, it can be repulsive if some conditions are satisfied. In this study, we showed that the prevention of the adhesion and the reduction of the friction can be realized using the repulsive Casimir force. In particular, we focused on the levitation of a metallic particle near an air-liquid interface and theoretically investigate the Brownian motion of the levitated particle. Furthermore, we proposed a new method to measure a mass of a single particle levitated within a suspended droplet.
