Chameleon-like ‘intelligent’ skin
The chameleon at the power plant is one of those animals that change color to suit its environment. Now with the help of a special substance, scientists have developed a “smart skin” that changes color in the sun.
Experts at Emory University have accelerated with the help of photonic crystals. Professor Yixou Dong, who created it, says he saw the changing chameleon and thought about making it something that was thoroughly researched. Another scientist associated with the study, Khalid Slyta, said that photogenic crystals were used for this purpose and that the skin could be used in stickers to prevent chemo-filamentation, chemicals, and counterfeiting. Although the work is in its early stages, it is also new and unique. Extremely fine photonic crystals were applied to water-rich elastic polymers so that the color-changing skin is called hydrogel. As the hydrogel is shrinking and spreading, the distance between the photonic crystals becomes more and more uniform and they change color. Iron oxide was added to the photonic crystal to further improve, so it didn’t matter to the amount of skin, but enough was that the temperature changed its color. This invention is referred to as the ‘stress smart screen’ or ‘SASS. When the sample is kept in the sun for 10 minutes, it turns orange-green, but its length and width do not matter. With this invention, soldiers will be able to produce color-changing clothing and other accessories…
