Bioinspired avian feather designs

Avian flight feathers have developed, through evolution, an intricate architecture with multi-functional structures that are essential for flight. These lightweight and resilient appendages motivate the invention of bioinspired designs. Here we fabricate various structures inspired by significant concepts identified in the feather vane and shaft. Bioinspired prototypes based on the feather vane's unique adhesive mechanism and directional...
