Transmitting power is much more difficult than transmitting information. The problem is difficult, but its solution could make the use of mobile electronics gorazco.fme more Researchers are committed to laboratory research to achieve this goal. Specialists from the University of Sejong (Korea) use an infrared laser for this. Their technology shows promise and has already proved the possibility of practical application.
Light with a wide wavelength of 1550 NM is realized by absorption, which is doped with erbium. Connecting the air of the receiving device, the main components For the natural operation of the system, the presence of a direct presence. With the development of an obstacle, the automation of the systems transitions to s s s s s s s s s s s s s s s s s s s s s s s s
The first tests were completed successfully. The developers managed to transmit 400 mW of energy at a distance of 30 meters. The photodetector was able to convert the received radiation into a current of 85 mW. Of course, this is not enough, the second inventions have that the characteristic of the system can be brought up to up to up to dd. Its advantages include the absence of the need to configure the receiving part, and the equipment can be placed at an older age without additional training.
