Scientists Use New Silk Materials To Develop "Invisibility Cloaks".

Reported that in the magic movie, Harry Porter was wearing a body.

Research

In a recent study published in the Journal of new materials, the researchers said that they used a new material obtained from silk and coated with a gold coating on their surface to create a cloak that could make people invisible after wearing.

Scientist

Fiorenzo Omenetto, Professor of Biomedical Engineering at Tufts University, said that although scientists had made invisible cloaks using glass fibers not long ago, invisible cloaks made of fiberglass had their inevitable shortcomings.

Fiorenzo said, as we all know, the cloak can stealth the principle of bending the light around the cloak, just like a stream flowing around a stone, so that people can not see the object in the cloak and cloak.

Though glass fiber is easy to do this by principle, such a cloak is too rough, it will be very uncomfortable after wearing, and it can only pmit a certain band of light, not completely stealth effect, cloak will be easily seen by the human eye.

The invisibility cloak made of silk silk completely solved the problem of the glass cloak.

The research team boiled the silk into boiling water and got the main material, silk protein.

The researchers then made the silk protein into a 1 cm square piece and smeared with a gold based "resonator" - consisting of about 10 thousand gold plates.

In this way, through the fine structure of silk and the coating on the gold resonator, it will be able to refract and distort the light of all bands, achieve complete invisibility effect, and is also very comfortable to wear.
