GECKO
Attach gecko-style
The gecko – Gekkota – has an amazing ability to climb vertical surfaces and even hang upside down. Adhesives are amongst the nastiest compounds used in design for glueing, however the gecko has inspired an adhesive based on physic and has also shown the possibility for humans to climb walls. Its clinging ability and strength have inspired adhesive applications that leave no residue and are not toxic. The way it achieves this amazing adhesion is by having millions of tiny filaments on its toes that wrap around any slight texture it can find. If you look at a close up of each toe, you will see that it has millions of tiny keratin hairs called setae on the surface of each foot. Each hair acts as a sort of suction cup, and collectively, millionsof these hairs produce a powerful adhesive effect.
