Ultrafast Elastocapillary Fans Drive Swift Moves in Ripple Bugs and Robots

Speedy Summary

• Rhagovelia ripple bugs utilize specialized middle-leg fans designed with a flat-ribbon architecture.
• these fans enable the bugs to navigate the surfaces of fast-moving streams effectively.
• The directional stiffness of the fan allows for rapid, passive elastocapillary morphing, functioning independently of muscle use.
