Wireless charging technology, on which we put our phone on a platform, has gradually become a new standard these days. On the other hand, the world of technology will completely eliminate cables and these stands. air charging technology also continues to develop. Big news came today about this technology, which Xiaomi previously announced it was working on.

According to a new study published in the journal Optics Express, scientists have set a new record for charging distance in air-charging technology. Scientists using infrared lasers, with infrared light from lasers Managed to charge a device 30 meters away. The total power obtained from the light at a distance of 30 meters, 85mW declared as.

For now, only small devices can be charged:

The power drawn from the system was more than adequate, especially for charging devices such as small sensors. Moreover, this power was achieved with extremely small hardware, as you can see in the photo above. The size of the photovoltaic cell coated receiver, which converts the light from the laser into charging power, is It was only 10 millimeters in diameter. So the receiver was so large that it could easily fit into almost any electronic device.

The light emitted by the laser does not pose a health hazard. While the central wavelength of the laser is stated as 1550 nanometers, this value is in the safest part of the infrared spectrum is located. In other words, the light from the laser cannot damage human skin or eyes. The next step for scientists, of course, is to get enough power to charge smartphones and other large devices.

The technology that Xiaomi introduced last year:
