2023: Product Announcement
In early December 2023, Chinese researchers from Wuhan University demonstrated a material called InvisDefense, which allows objects to be made invisible. The technology can also be used to create new masking tools.
The invisibility effect is achieved by using a biconvex mesh formed from an array of small cylindrical lenses. Their characteristics are selected in such a way that light is regularly refracted, as a result of which the object located behind such material seems invisible.
Earlier, experts from Wuhan University presented the InvisDefense invisibility cloak, which hides a person from CCTV cameras based on artificial intelligence. Moreover, such clothing retains camouflage properties both in the visible and infrared radiation ranges. In particular, during the day, the product misleads AI cameras by using an additional camouflage pattern with a special design. In the dark, when observation is carried out in the IR spectrum, special wiring that generates heat comes into effect. As a result, the means of machine vision cannot determine the presence of a person.
The developers believe that their technology will form the basis of new means of protecting personal life and ensuring privacy. Tests have shown that the use of the invisibility cloak reduces the accuracy of detecting people using AI cameras by 57%. The algorithm could prove useful in developing new AI applications, allowing researchers to more effectively identify potential vulnerabilities. On the other hand, such means can mislead automotive autopilot systems and safety complexes, which poses a threat to the health and life of citizens.[1]
