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

According to foreign media reports, Harry Porter has been wearing a magic film. invisibility cloak He sneaked out of Hogwarts School of witchcraft and found unheard secrets. Having such invisibility cloaks has become the aspiration of many. Recently, scientists have made use of silk It has created a real invisibility cloak. For a long time, people used silk to make noble and comfortable clothes. But it is not thought that this kind of clothing has been used for thousands of years to make invisibility cloaks. This invention has made things that are possible only in science fiction go to real life.

According to a research report published in the recent journal of new materials by researchers at Tufts University and Boston University, they used a new material obtained from silk and coated with a gold coating on their surface to create a cloak that can invisibility after wearing.

Fiorenzo Omenetto, a professor of Biomedical Engineering at the Tufts University, said that although scientists had made invisible cloaks using glass fibers not long ago, the invisibility 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 transmit 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 texture on it. resonator "- there are about 10 thousand small pieces of gold stamped. 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.

Professor Fiorenzo Omenetto began to study silk three years ago. He said that making invisibility cloaks with silk is only a potential use. The most useful use of silk is to make use of it in the medical profession. Not long ago, he made use of silk to make an optical and electronic sensing device that could be implanted into human body to monitor the recurrence of cancer. Doctors in the radiology department can also use silk materials to make certain organs invisible, thus facilitating their examination of tissue lesions hidden beneath the organ. He predicted that silk materials will be widely used in the medical field in the future. By that time, a small silk can help us save lives.
