Gecko-hand-gloves helps human climb wall like spiderman

Geckos can run just as easily along a wall or ceiling as they can across a floor. This is due to special pads on their toes, which can even grip glass. No man-made adhesive technology comes even close to functioning as well as gecko feet. Credit: Institute for Creation Research

Watch out, Spiderman! Stanford engineers recently demonstrated a pair of  gecko-inspired hand pads strong enough to pull the weight of an adult man and to allow him to climb a wall. Scaling walls like a gecko At the center of the gecko’s clinging ability are its specialized pads, located on the reptile’s toes, comprised of various satae (bristle- or hair-like structures ) on the…
