South Korean scientists have developed a new laser wireless charging system. The technology can transmit energy over 30 meters. Many years ago, Nikola Tesla worked on a wireless energy transmission system that would allow it to be transferred to any corner of the planet. Scientists from around the world are now working to recreate this idea and are increasingly successful in this field. A team of South Korean scientists has developed a new laser charging system with very unusual capabilities. Technology using infrared, can wirelessly transmit energy to devices. The results of their research were published in the Optics Express journal.
The wireless charging system will change the way your equipment is powered
The system developed by scientists at Sejong University uses infrared light and enables the transmission of energy over a distance of 30 meters. Therefore, it can be a safer alternative to wired charging of our mobile devices, as well as powering equipment from the Internet of Things category installed in a given area. Scientists have been working on wireless power transmission over longer distances for years. Until now, however, the challenge has been to safely transmit power over the distance of a meter. South Korean researchers overcame this obstacle with a technique called distributed laser chargingseparating the laser transmitter and receiver from each other. In this way, power can be transmitted through light. AND when its beam crosses an object, the system automatically switches to energy saving mode. Thanks to this, the technology is completely safe for humans. Unlike other solutions that require the receiving device to be on the charging stand or to be stationary, the new technology has no such limitations. The laser scattering allows self-regulation without tracking processes, as long as the transmitter and receiver are in sight. The technology of wireless powering devices will eliminate the need to carry chargers for our smartphones. The solution can also be used in factories, where the need to install electrical installations to power devices will disappear. The technology can be particularly useful in environments where electrical connections may cause interference or create a fire hazard. Of course, the technology is not yet ready for commercial use. Currently it can deliver only 400 mW of power over a distance of 30 m. This is enough to charge the sensors, but for now it is impossible to charge portable equipment due to insufficient power. Scientists, however, intend to continue developing it to increase the power transmitted in this way. Perhaps in a few years it will be possible to refine it enough to be able to charge our phone wirelessly.
