Active matter is a materials and objects that have autonomous motion mechanisms and interact with each other. For example, animals, living cells, and bacteria are classified as active matter. The dynamic performance of various animals and insects that walk and propel themselves on the water surface is mainly related to the surface tension. On the other hand, there are few examples of research that utilize the photothermal conversion of liquid metal as a power source for active matter. In this study, the bent elastomeric film containing liquid metal was floated on the water surface, and the marangoni propulsion and meniscus climbing induced by near-infrared light (NIR) irradiation was verified by kinetic analysis.
