Have you ever felt the urge to become invisible to the world for a few minutes? The good news is that science can help you with that.

In 2015, scientists used gold nanofibers, called nanoantennas, to produce a three-dimensional object capable of bending light passing through it.

This was the first time that a three-dimensional object was arbitrarily hidden from visible light. However, the piece was microscopic in size.

In 2018, it is the turn of Canadian scientists to delve into the world of disappearance. They managed, for the first time, to make an object completely invisible when illuminated with full spectrum light.

The essence of this technique is to convert light frequencies into regions of the spectrum that will not be affected by light propagating through the object. For example, converting light in the green region of an object into the blue part of the spectrum.

An article published in 2021 in Advanced Materials showed that South Korean researchers were also developing something like this.

The hood uses dynamic cooling and heating of its surface to confuse thermal vision cameras.

For conventional cameras, the housing is covered with a mixture of pixels and liquid crystals that can individually change color.

The skin still does not recognize the colors around the user, which is necessary to enter them. The research team plans to integrate a small camera so that the equipment can work independently.
