Chinese scientists have created a smart window

In China, scientists invented a smart window with autonomous food. The device can be transparent or muddy. And also able to work without charging for several days. This is reported by Nano Energy Edition.

The most important feature of the window is that it can change the light entering the room. Glass can block ultraviolet rays and infrared light, becoming opaque. Thus, it reduces the amount of sun rays.

In addition, the gadget independently generates electricity through mechanical and radiant energy.

The window transparency varies with one press of the button. The windows are powered by a tribelectric nanogenerator – Teng.
