livescience.com – Tue Feb 2, 5:50 pm ET


A new high-tech suction device could allow humans to walk on walls like Spider-Man or create adhesive devices that could be turned on and off with the flick of a switch.

The contraption, inspired by a beetle that can hold on to a leaf with a force 100 times its weight, uses the surface tension of water to make an adhesive bond, but it does so with a creative twist. It could be used to create sticky shoes or gloves, researchers said today.

The device consists of a flat top plate riddled with tiny holes, each just a few hundred microns (a millionth of a meter) wide. A bottom plate holds water. In between is a porous layer. A 9-volt battery powers an electric field that forces water to squeeze through the tiny holes in the top layer.

The surface tension of the exposed droplets makes the device grip another surface - much the way two pieces of wet glass stick together. Turn the electricity off, and the bond breaks.

Yeah, I doubt the glue on the wallpaper would be strong enough to hold a full grown man. ]]> http://freakangels.com/whitechapel/comments.php?DiscussionID=7712&Focus=218665#Comment_218665 http://freakangels.com/whitechapel/comments.php?DiscussionID=7712&Focus=218665#Comment_218665 Sat, 06 Feb 2010 23:58:00 -0800 Brendan McGinley http://freakangels.com/whitechapel/comments.php?DiscussionID=7712&Focus=218671#Comment_218671 http://freakangels.com/whitechapel/comments.php?DiscussionID=7712&Focus=218671#Comment_218671 Sun, 07 Feb 2010 01:33:58 -0800 rough night
