Researchers Create Camouflage Tech Modeled After Octopus Skin
A group of researchers created camouflage tech inspired by octopuses, cephalopods that can change the color of their skin depending on their surroundings, National Geographic reports.
The team, led by Cunjiang Yu at the University of Houston and John Rogers at the University of Illinois, created a sheet that can detect light falling on it and change color accordingly.
The device’s speed is still nowhere near as swift as an actual cephalopod.
According to the outlet, octopuses and other cephalopods have three layers of skin, one for displaying warm colors, one for display cool colors, and one that “[diffuses] white light in all directions.”
While the so-called adaptive optoelectronic camouflage only displays in black and white, it does take the same layered approach as mother nature.
According to the research paper, published in the journal Proceeding of the National Academy of Sciences, the faux octo skin has “a color-changing element on top of a white reflective surface, an actuator, and a light sensor, all on a flexible plastic support.”
The researchers hope they’ll be able to improve upon the current device by adding color to the device and making it more energy efficient, though they’re aware it’s going to be hard to achieve the same level of camouflage as that of an octopus.
