The clever design “is inspired by geometric patterns found in leaves,” one scientist said of the solar-powered devices.
have developed adorable little electronic “microfliers,” the size of a postage stamp, that fold like origami paper in midair to change their flight pattern.
After being dropped from a drone or other high-altitude object, the microfliers depend on the wind to disperse. When the origami base is fully open, the wind catches them and moves them like an autumn leaf.according to the Wednesday report in Science RoboticsMicrofliers use an origami folding pattern, inspired by tree leaves, to change how they move through the air.
“We combine the Miura-ori fold, which is inspired by geometric patterns found in leaves, with power harvesting and tiny actuators to allow our fliers to mimic the flight of different leaf types in mid-air,” Vikram Iyer, assistant professor in the Paul G. Allen School of Computer Science & Engineering at UW,“In its unfolded flat state, our origami structure tumbles chaotically in the wind, similar to an elm leaf.

Battery-free robots use origami to change shape in mid-airResearchers have developed small robotic devices that can change how they move through the air by 'snapping' into a folded position during their descent. Each device has an onboard battery-free actuator, a solar power-harvesting circuit and controller to trigger these shape changes in mid-air.
