Inspired by the dynamic color-changing properties of squid skin, researchers have developed a method to manufacture a heat-adjusting material that is breathable and washable and can be integrated into flexible fabric. The composite material operates in the infrared spectrum and consists of a polymer covered with copper islands. Stretching the material separates the islands and changes how it transmits and reflects infrared light; this innovation creates the possibility of controlling the temperature of a garment.
