Fig. 5: The feathered wing was constructed using electrostatic adhesive materials and compared against a baseline airfoil shape and rigid plate wing in a wind tunnel.

Fig. 5

A The top of each 3D printed feather was coated in an aluminized PET, and the bottom was coated with a polybenzimidazole film to generate coulombic and Johnsen-Rahbeck adhesive forces when subjected to high voltages (150−300 V). B The feathered wing was compared to a rigid baseline and plate wings, each mounted vertically in the wind tunnel with a baseplate on the mount side.
