Scientists Create ‘Invisibility Cloak’ Inspired by Squid Skin.
Humans have long sought ways to disguise themselves, and as technology advances, we have to be more and more creative to do so. The newest experiment in invisibility comes from University of California, Irvine where scientists were inspired by a natural phenomenon: the changing colors of squid skin.
Squids are able to perform this thanks to pigment in their cells that can expand or contract to change their color. At Irvine, scientists found a way to replicate this action. The team dropped dots of aluminum onto a stretchy polymer surface. When the aluminum was expanded, it reflected more infrared light than when it was condensed. This unique capability won’t can’t hide a wearer in plain sight, of course, but it could hide them from prying infrared eyes.
The researchers tested this by placing their new invention, cut into the shape of a squid, on a warm surface. When the aluminum dots were expanded, the skin reflected more infrared light than its surroundings, making it visible to a camera. But in its contracted state, the skin blended in and wasn’t visible on the camera.
This squid-inspired invention might save lives. Using this technology, scientists could create camouflage that works against infrared cameras. It will be very handy when it comes to hiding from the Predator.
