The most surprising characteristic of the gecko is its ability to walk effortlessly on any kind of surfaces, vertically, or upside down, even on the ceilings. And he does it although its feets and fingers are not adhesive and have no form of suction cup.
Man has been trying to explain this behavior for centuries! Even since the 3Th century BC ! Aristotle, THE Greek philosopher, wrote about the gecko: " He climbs very fast on trees, and in all directions, even upside down ". (History of The Animals, book 9, translation Barthélemy Saint-Hilaire).
After years of researchs, and many hypothesis, the secret of geckos agility has been revealed and it should allow for new technological advances in adhesives, even developing new applications for space programs.
