The UCSD cloak attracted such significant attention due to its unique design which allows the invisibility shield to be lighter and cheaper than any other cloaking technology currently under development. The UCSD team has been in contact with a Defense Department liaison and is preparing to submit a proposal detailing their cloaking technology, reports the Army Times. It was because we saw something cool and were like ‘I wonder what a cloak would look like.’ And we couldn’t build a cloak because it was too much material, so we made a jacket.Image used with permission by copyright holderResearchers from the University of California-San Diego have created a breakthrough invisibility cloak that has caught the attention of the Defense Department due to its ability to hide objects from the naked eye. It wasn’t because I wanted to take over the world with thermal camouflage. “It wasn’t because I wanted to write a paper. “This idea fell out of childish enthusiasm,” he added. To Tidball, this experiment was a proof of concept and a pipe dream come true. “You’re not gonna see it on the street or on a military jet tomorrow,” he said.

Vollebak has even managed to use it to play games like Snake and Tetris, as demonstrated in a video posted on its YouTube channel. These graphene patches are similar to those that compose some new experimental screens, just much bigger and on a jacket. We trick the camera by changing that heat by applying a voltage to graphene.” The amount of thermal radiation coming off that thing. “You trick the camera by changing the amount of heat something is emitting. “If you want to make something or someone invisible to an infrared camera, you effectively have to trick the camera,” Tidball explained. The change in radiation can be used to make the wearer appear "invisible" by appearing hotter or colder to fit in with the surrounding environment. Gold and copper wires connect the patch to a microcomputer, which programs the patches to emit different levels of thermal radiation without actually increasing the temperature. The coat consists of 42 “graphene patches,” which have hundreds of atom-thick layers of graphene. Their collaboration is what yielded the thermal camouflage jacket. In 2019, Tidball and his co-founder (and twin brother) Nick started working with Coskun Kocabas, a professor of 2D Device Materials at the University of Manchester who had co-authored a paper on the use of graphene for thermal camouflage. But graphene has other potential applications. In 2018, Vollebak started making jackets made out of graphene, a highly tunable material used in many electronics. Realizing this, Volleback decided to work with scientists to create a garment that could thermally camouflage the wearer. Such approaches may be easily defeated by thermal imaging, which registers the temperature of people and objects. The key idea behind the jacket is that the optical portion of an invisibility cloak-hiding an object from the human eye-is only one part of the puzzle. “We’re really interested in what are the challenges human beings will face in the next century on this planet and other planets, and how we make clothes for them.” “Our fundamental mission is to make clothes for the next century,” Vollebak co-founder Steve Tidball said.
