Specialists of the French company Dracula Technologies have developed charging for smartphones, which works from natural and artificial light. It is a small folding sheet, which is in an hour can be printed on an ordinary inkjet printer and pasted to your phone or any other surface.

Dracula Technologies specializes in solar energy. In the new project, they decided to use artificial lighting, futurist.ru reports. With him, the creators and difficulties arose, because the intensity of artificial light is much lower than the intensity of the sun. While the developers cannot fully charge the phone with the help of electric lighting, but their work is quickly improved. Engineers promise that in a few months they will be able to charge smartphones with artificial light for a short period of time.

The device itself - a sheet - consists of five layers, the average of which is photoactive. The minimum size - 5 centimetres in diameter - is quite suitable for modern smartphones, but the creators advise printing more sheets (up to 30 centimetres) and fixing them on those surfaces that often come into contact with light. The sheet can change colour and even become transparent, so it can be safely worn on a T-shirt.

But the creators are not going to stop on charging for smartphones. They are confident that their convenient, small and cheap development will soon be used to charge all small electrical appliances.
