It’s not Harry Potter’s invisibility cloak, but new findings could enable a chameleon-like style of camouflage.
Researchers at the University of Michigan have devised a technique as part of a study that can change the color of a crystal structure by manipulating its particles with ultraviolet light, a process that has the potential to be used for concealment.

The colors of a crystal structure are based on the space between its particles. This space (or lack thereof) decides what light the crystals will absorb, and what it will reflect, a process that manifests itself in visible color. Knowing this, researchers realized that if they manipulated the space between the particles, they would be able to control the color of the crystals. Read more…
