Gecko-Inspired Dry Adhesive Set For Space

AndreV writes "Biomimetic adhesives aren't new, but a PhD graduate in British Columbia has developed a new method of creating microscopic, mushroom-like plastic structures in order to produce a dry adhesive that mimics the stickiness of gecko feet—and is prepping his glue-free innovation for outer space. A research group at his university, in collaboration with the European Space Agency, is engineering a spider-like, sticky-footed climbing robot destined to explore Mars, and it is also developing reusable attaching systems for astronauts to use where magnetic and suction systems generally fail. In the future, he says, single-use versions could be used in any number of medical applications as well as for replacements for everyday sticky needs, such as Post-It notes and Scotch tape."

A friend of mine studied this stuff for his Ph.D research. It's the molecular-level adhesive force between the Gecko's feet and the surface that allows it to cling. That force is relatively-weak but when multiplied by a few million "pads" on the foot, it's strong enough to let a lizard climb up a wall. Or a robot.
