Among all the superpowers that children fantasize about having, one of the most repeated over the years is being invisible. Until now, this ability was unique to fantasy series and movies, however, a group of engineers from the Faculty of Sciences at Donghua University (China) has managed to make this goal a reality, but not using magic, but through science.
It was last year when Chu Junhao, physicist and director of the faculty we just mentioned, presented one of the most interesting and curious advances we have seen this year during a scientific event held in Shanghai.
This is the presentation of one of the advances that this university in China is working on the most, invisibilityand just as if it were a Harry Potter movie, during the presentation this academic referred to the project as “a cloak of invisibility.”
With the help of two people, Junhao came out on stage with a sheet that was initially translucent, since his legs could be seen from behind, although somewhat blurry. But the spectacular thing did not come until the assistants They turned said sheet at 90º and the physicist’s legs disappeared.
As Junhao himself explained, this is not a magic trick but rather this sheet was composed of a grid made of small convex cylindrical lenses what they achieve change the direction of light making images behind them too small to be perceptible to the human eye, thus creating the effect of invisibility.
For now this is only a project developed at a university, but its creators do not want to fall short of the magnitude of their discovery and as the academic himself assured “In the future, everyone will have Harry Potter’s invisibility cloak in their closet.”
The truth is that after these statements alarms are raised a bit about this advance, since in the absence of examplesthe mind only takes us to the bad uses that could be made of this “invisibility cloak”, in addition to the fact that until now The development of this technology was focused on military usessuch as to create a layer for fighter planes or make military cars undetectable.
