Thermal vision cameras detect differences in temperature by sensing infrared wavelengths. If a coating could be developed that showed dynamic tuning of the effective temperature, it might be possible to hide objects from infrared sensing. By drawing inspiration from squid skin, Professor Alon Gorodetsky and his colleagues at the University of California, Irvine developed adaptive infrared-reflecting structures that feature robust mechanical properties,...
