Synthetic two-sided gecko's foot could enable underwater robotics

Geckos are well known for effortlessly scrambling up walls and upside down across ceilings. Even in slippery rain forests, the lizards maintain their grip. Now scientists have created a double-sided adhesive that copies this reversible ability to stick and unstick to surfaces even in wet conditions. They say their development could be useful in underwater robotics, sensors and other bionic devices.
