| Outline of Final Research Achievements |
Active matters, which can move through energy dissipation like living organisms, have been actively investigated. We adopted simple systems which can be simply discussed from the viewpoint of physics in order to obtain general understanding for such motion. For example, we investigated a camphor particle, which makes surface tension gradient around itself and moves due to the gradient, and a droplet of chemical reaction medium where interfacial tension gradient arises due to the chemical reaction inside it. We proposed the mechanism of these systems, and discussed the relation between the shape and motion. As a result, we found that the shape of the object essentially affects the motion.
