A light-driven flying balloon has been fabricated using multi-walled carbon nanotube (MWNT) composite films, of which thickness and density are approximately 6 µm and 0.5 mg/cm2, respectively. The shape of balloon is a regular tetrahedron with approximately 11 cm length on a side. By irradiating light using a tungsten lamp to the balloon, the balloon can be levitated like a hot-air balloon because the temperature of MWNT film is rapidly increased and the temperature of air inside the balloon is gradually increased. We confirmed that the maximum levitation height is ap-proximately 14 cm during light irradiation. The balloon developed in this study could be utilized for a flying platform of autonomous flying monitoring system.
