No Ink, No Dye — Just Pure Science!🦚 IISc's Colour-Changing Film Explained!

🧠 IISc Bengaluru's Latest Scientific Breakthrough!
Researchers at the Indian Institute of Science (IISc), Bengaluru, have developed a revolutionary colour-changing film that works without using any ink or pigments! 🌈 Inspired by peacock feathers and powered by nanotechnology, this soft, stretchable film changes its colour based on how much it's stretched.

Unlike traditional displays that use dyes or backlights, this material manipulates light itself through nanostructures and liquid metal nanoparticles (Gallium). It behaves like a gel, can be printed like an ink, and could transform future wearable displays, security labels, camouflage materials, and even medical sensors.
