Become invisible as the young wizard Harry Potter, walking incognito in the school Hogwarts, is a dream that could become reality, much sooner than we think! Indeed, the United States, a group of scientists has managed to develop an invisibility cloak microscopic able to make a completely visually undetectable object.

This is a first for science. A team of US scientists who belong to the Lawrence Berkeley National Laboratory, in California, managed to make disappear a three-dimensional object under a thin layer of just 80 nanometers thick. With a size for the microscopic point, the same technology could be used to design a "cape" much larger, which would be able why not conceal a person or a much larger object.
"This is the first time an object in three dimensions some form has been made invisible," said Xiang Zhang, the acting director of the Materials Sciences Division at Lawrence Berkeley National Laboratory. "Our ultra-fine layer now much like a cape. It is simple to design and operate and can be manufactured in sizes to cover normal macroscopic objects, "he added.
This "cap" is composed of gold elements covered by a magnesium fluoride layer. Very thin and very flexible, it allows to perfectly fit the object on which it is mounted. A test was performed with an object having 3 bumps, it became undetectable optically.
A completely undetectable object
The "capes" invisibility designed to date do not cover the object completely undetectable to make a difference was visible with the immediate environment. In addition, they were too bulky, says the scientist: "If you want to hide your body, you would have to wear this thing that is three to four times the size of your body with you wherever you go".
There is still some way to go before creating a "cape" that can adapt to all sorts of objects admitted scientists, it has indeed been designed according to the object to hide, but researchers are on track!
