Octopuses and cuttlefish are well known for their astonishing ability to change colour almost instantaneously. Can we copy this system to create an automatically camouflaging material? John Rogers from the University of Illinois explains to Georgia Mills how these underwater animals have inspired this new technology.
What I want to know is how a flatfish manages to mimic the texture of the ground underneath it. It doesn't have eyes in its belly, and even if it did, there's no light under a bottom-resting fish, so it has no apparent means of knowing what it is supposed to replicate. Yet they do so remarkably well. alancalverd, Mon, 15th Sep 2014
I wonder if the eyes of bottom-dwelling species can see the surrounding seafloor, and that is enough for it to produce a similar-looking texture, allowing it to blend in?
I've seen the color change in many camouflaging sea creatures and the change is near instantaneous across the entire body. I wonder if it can instruct us on intercellular communications that must be occurring. Some stimulus spreads with lightning speed throughout the cells of the creatures skin, without interfering with normal metabolism of the animal. I think if we can get a better handle on the intercellular communication, we would advance the science of limb and organ regeneration. Expectant_Philosopher, Sat, 20th Sep 2014
From a technological view point we could do anything from alter the hue of pigments to photographing a background and reprinting it onto the camo.
What about using something like
I have come up with a realistic "Active camouflage" concept, which I came up with a long time ago. In fact I posted the Idea here about a year ago.
