    Smart Windows Self-Illuminate on Rainy Days

    Article obtained from Photonics RSS Feed.

    A joint research team has developed a technology that will allow windows to change colors according to the amount of moisture, without the need for electricity.

    The researchers developed a variable color filter using a metal-hydrogel-metal resonator structure using chitosan-based hydrogel, and combined it with solar cells to make a self-powering humidity sensor.
