Chinese scientist demonstrates 'invisibility' ability using special materials

At a super science event of the Chinese social media platform bilibili held on the evening of October 28, Mr. Chu Quan Hao, an academician of the Chinese Academy of Sciences and infrared physicist, demonstrated his ability to 'invisibility', making his legs disappear with the help of a magical material called 'Lentilating Grating' (or lenticular mesh) , leaving the audience in awe.

The material consists of rows of small cylindrical convex lenses, which cause light to refract in a regular and regular manner. Each cylindrical convex lens compresses the object behind it into a thin strip, making it appear invisible, thereby achieving a visual 'invisibility' effect.

Speaking here, he said: 'Whether in real life or in the natural animal world, there are many invisibility spells. This is not magic, but a scientific method. In the future, Harry Potter's invisibility cloak will become an everyday item in the wardrobe.'

In addition to the above method, Academician Chu Junhao also demonstrated another invisibility method - using two substances with similar refractive indices . For example, the refractive indices of high borosilicate glass and glycerin are similar, when an object made of high borosilicate glass moves in glycerin, it can also achieve an invisibility effect. This method opens up even more possibilities and shows the magic of invisibility technology.

According to this expert, this is actually one of the principles to realize the 'invisible cloak' , when the fabric of the clothes and the refractive index of the air are equal, people can freely 'be invisible' after wearing it.

He also added that current cutting-edge discoveries in 'invisibility' can not only avoid the naked eye, but also avoid infrared surveillance.

Mr. Chu Quan Hao believes that in the future, with the gradual improvement of technology and 'super materials' , the ability to 'invisibility' in science fiction works will gradually become reality. Many 'invisible' devices can change people's lives, such as invisible rooms with better privacy and invisible hearing aids.

However, in addition to being excited about the new invention, many Chinese netizens are also concerned about this technology falling into the hands of criminals and hope that the law will be improved to prevent similar situations from happening.
