Abstract
Inspired by dandelion seeds, this study demonstrates light-driven microfliers using ultralight, super-sensitive tubular bimorph soft actuators. The microflier's falling velocity is controlled by light irradiation, enabling mid-air flight with a sustained time of ~8.9 s and a maximum height of ~350 mm. The microflier exhibits light-driven upward flight with customizable clockwise or counterclockwise autorotation.
