| Popis: | In this Letter, a water-in-oil swimming droplet’s transition from straight to curvilinear motion is investigated experimentally and theoretically. An analysis of the experimental results and the model reveal that the motion transition depends on the susceptibility of the droplet’s direction of movement to external stimuli as a function of environmental parameters such as droplet size. The simplicity of the present experimental system and the model suggests implications for a general class of transitions in self-propelled swimmers. 泳ぐ水滴はなぜ直進しないのか？. 京都大学プレスリリース. 2021-08-23. |
