Harry’s invisibility cloak
Dreams came true
Good or bad, it does not matter what the situation is, you may need to isolate yourself from the rest of the world. Actually, it could be better if we could just be invisible, but be aware of everything around us. Hence, we could have a chance to get ready for every action against us, or at least we could easily understand who does good or bad things behind us.
Unfortunately, we are not as lucky as chameleons. They can change their color to communicate with each other, camouflage themselves and control their body temperature.
However, we are quite smart to figure out the marvelous feature of chameleon skin and copy it to build an invisibility cloak!
You don’t need to be jealous of Harry’s invisibility cloak anymore!
Researchers in Cambridge have already developed an artificial ‘chameleon skin’ which could be used in the application of camouflage.
The color-changing skill of chameleons stems from the presence of chromatophore; skin cells. These skin cells have connected contractile fibers that make it possible to move pigments around. When skin is exposed to light, the pigments are spread around to display the color or they squeezed together just to make the cell clear.
The developed artificial chromatophores in Cambridge work based on the same principle but instead of having contractile fibers, color-changing ability depends on the light-powered nano-mechanism and micro drops of water act like cells. These microdroplets contain gold-coated nanoparticles in a polymer shell and the geometry of the nanoparticles determines which color appears. It is possible to see the color change of this fantastic material when it is exposed above 32 C.
So, the thing you have imagined today might be the reality of the future! Science proves this fact every day with new studies.
