Walk on walls with sticky device

SPIDEY’S SECRET OUT
Washington: It may soon be possible to walk on walls like Spiderman with American researchers claiming to have invented a device that could lead to development of shoes or gloves which would stick and unstuck to walls and also bear load.
Researchers at Cornell University have created a palm-sized device that uses water surface tension as an adhesive bond, journal proceedings of the National Academy of Sciences reported on Wednesday.
According to lead researcher Paul Steen, the device, using rapid adhesion mechanism, could lead to such development of the shoes or gloves that stick and unstick to walls, or post-it-like notes that can bear loads.
The team took inspiration from a beetle native to Florida, which can adhere to a leaf with a force 100 times its own weight, yet also instantly unstuck itself. The device consists of a flat plate patterned with holes, each on the order of a micron (one-millionth of a meter).
A bottom plate holds a liquid reservoir, and in the middle is another porous layer. An electric field applied by a common 9-volt battery pumps water through the device and causes droplets to squeeze through the top layer.
The surface tension of the exposed droplets makes the device grip another surface, in a manner similar to the way in which two wet glass slides stick together.

Very attractive invention, but restriction required for it’s use. much better only use in defense sector to avoide unauthorized or public mis use.
