Scientists create chameleon-like invisibility material that doesn't use electricity

Chinese researchers have developed a color-changing material mimicking chameleons. The "self-adaptive photochromism" (SAP) technology uses a light-sensitive molecular compound to reconfigure without external power. The material adapts to colored environments within 30-80 seconds and can be applied as a sprayable coating. While blue and purple tones are challenging to replicate, the innovation shows potential for fashion, encryption, and stealth applications.
