The invisibility jacket will come true

Futuristic clothing brand Vollebak presented a prototype of a primitive thermal invisibility jacket developed in collaboration with scientists. If it was only operating on the infrared spectrum at the moment, it might one day become a true invisibility cloak.

a invisibility cloak It would be of little use if it did not hide the wearer in the infrared spectrum. A simple thermal camera will be enough to detect anyone trying to hide. Based on this observation, the researchers decided to focus their efforts first on the thermal radiation of the human body. The garment thus produced is a proof of concept and the result of a collaboration between National Graphene Institute from the University of Manchester in the United Kingdom and VollebakA futuristic clothing brand.

Instead of the head, the researchers chose Jacket Which requires less materials. It is covered with 42 squares consisting of more than a hundred layers of graphene. Each square can be controlled as a pixel Across Gold and copper wires, programmed using a microcontroller built into the casing. Thus, they can modify its heat radiation without changing its temperature.

By applying an electric voltage to the squares, the ions are pushed between the layers of graphene with ionic liquid. The higher the number of ions, the less heat radiation emitted from the box and the cooler it appeared. Since each square can be programmed individually, by increasing the number of squares and decreasing their size, it will be possible to blend them into the background, at least for the thermal camera. So the quality of invisibility cloaks could one day be judged by their dissolution…

The casing is theoretically not limited to the infrared spectrum. According to the researchers, with sufficient energy, it is also possible to change color graphene in the visible spectrum. Thus, this technology has the potential to become a true invisibility cloak one day, even if it isn’t tomorrow.
