It even works in infrared.
A team of researchers in South Korea are developing an artificial "skin" that could allow soldiers to perfectly blend in with their surroundings. Such a cloak could make them invisible not only to regular cameras, Defense One reports, but infrared-based night vision ones as well.
The skin, as detailed in a new paper published in the journal Advanced Functional Materials, can camouflage itself and is capable of cooling down or heating up depending on its surrounding environment, which could make future soldiers difficult to spot on thermal imaging cameras.
Individual "pixels" make up the device, each containing thermochromic liquid crystals that allow them to change their color.
In experiments, the team showed off their cloak's capabilities. A patch attached to the back of a hand turned blue for instance once that hand was placed on a blue surface.
The patch isn't yet capable of recognizing ambient colors. Their demonstrations still required them to manually input the surrounding colors, according to Defense One.
The team is however planning to integrate a "micro camera" next to allow for an "autonomously working device," as Seung Hwan Ko, researcher at Seoul National University and team lead, told Defense One.
Seung and his team are also planning to scale up their invention and allow the device to still function in extreme temperatures.
