Metamaterial Invisibility Cloak

Scientists have created a metamaterial-based invisibility cloak that replicates how cephalopods, such as squid or octopus, blend in with their environment and avoid predators. Basically, one side of the cloak has thousands of tiny light-sensitive cells that can detect surrounding colors, thus triggering electrical signals to imitate them by using heat-sensitive dyes, with the entire process taking a mere 2-3 seconds. “I have high hopes for its use in military camouflage. At the moment the military spends millions of dollars developing new camouflage patterns but they’re all static right now, they don’t change. If you put a pattern designed for the forest into the desert, it is not going to function. Dynamic camouflage would allow soldiers and their vehicles to adapt to their surroundings instantly,” said engineering professor Xuanhe Zhao, at MIT.
