Gecko foot
Gecko foot. Close-up of the foot of a New Caledonian crested gecko (Rhacodactylus ciliatus),showing the adhesive lamellae (ridges). Gecko feet use very small subdivided filaments on the lamellae to bond with surfaces at the molecular level using Van Der Waals' forces. Every square millimetre of a geckos footpad contains about 14,000 hair-like setae,each of which is tipped with between 100 and 1000 spatulae. Their structure has inspired scientists such as Dr. Autumn Kellar to adapt the structure for robotic designs. Gecko feet have the property of being self cleaning and very adhesive,without leaving any residue. The grip is so strong that geckos have to disengage their feet by curling their toes backwards,much like tape being peeled off
