New color-changing smart skin inspired by chameleons
- Scientists have developed a flexible smart skin that changes colour when it reacts to heat and sunlight while maintaining a near-constant volume.
- Photonic crystals in a chameleon's skin help the lizard change its appearance.
- Besides chameleons, many other creatures have evolved the ability to change colour. The stripes on a neon tetra fish, for example, turn from deep indigo to blue-green when they swim into the sunlight.
