Pixelated Broadband Camouflage

Shu Yang of the School of Engineering and Applied Science has developed an artificial chromatophore that can change colors on command by taking inspiration from active camouflage in the animal kingdom. Made from polymer networks of liquid crystals arranged in helical shapes, these membranes require less deformation to change color than previous models, which could lead to the creation of new highly sensitive biomimetic photonic devices and sensors.
