AKIPRESS.COM - An ultra-thin flexible material has been developed that can wrap around an object and make it vanish, reports MSN.

Although the "invisibility skin" has only been tested at microscopic scales, scientists believe it should be possible to create larger versions in the future.

The 80 nanometer thick film is made from gold "nanoantenna" blocks that interfere with the normal scattering of light waves.

In the test, the "cloak" was wrapped around a tiny lumpy and dented "bump" measuring 36 micrometres square – about the size of a few living cells. Once activated by switching the polarisation of the nanoantennae, it made the object invisible.

Lead researcher Dr. Xiang Zhang, from the U.S. Department of Energy's Lawrence Berkeley National Laboratory, said: "This is the first time a 3D object of arbitrary shape has been cloaked from visible light. Our ultra-thin cloak now looks like a coat. It is easy to design and implement, and is potentially scalable for hiding macroscopic objects."

In the Harry Potter stories, the boy wizard hides from his enemies using a cloak that renders the wearer invisible. It works by magic rather than the light-channelling "metamaterials" used by scientists.

Metamaterials have features smaller in size than the wavelength of light, allowing them to re-route incoming light waves.

Previous invisibility experiments have produced bulky, rigid designs that cannot be adapted to different environments.

The technology holds promise for applications such as high resolution microscopes, super-fast optical computers, and 3D displays.

However, it is still a long way from providing the perfect camouflage for soldiers and military vehicles, or allowing spies to creep around unseen.
