Wireless charging has become a feature of most high-end phones. because it is a very handy tool. However, when using this charging method involves placing the phone on a surface capable of transferring charge without the need for cables.
Very soon, this may no longer be necessary, because a group of Korean scientists from the University of Sejong managed to develop a new type of laser charger which works with infrared rays capable of charging a device up to 100 feet away.. This way, a person can hold their phone in their hand while it continues to charge without having to use a cable or lay it on a surface.
The development of this type of technology could lead to a system capable of automatically charging a phone when a person enters a room.. This will require the wireless charging system to be able to function similarly to how a router does by transmitting a WiFi signal.
The scientists responsible for developing the laser charger explained that the device consists of two parts: a transmitter that can be placed in a room and a receiver that can be built into electronic devices compatible with this technology.
They detailed that the transmitter uses an erbium-doped fiber amplifier, which is responsible for creating a beam of infrared light that is sent into the air to hit the receiver. consists of a retroreflector with a spherical lens in such a way that the process of charging the equipment begins.
It should be noted that if the line of sight between the transmitter and receiver is violated, the device switches to a reduced intensity mode.
Scientists have argued that The next step in his research, which has even been published in specialized journals, will be to improve the efficiency of photovoltaic cells so that they can increase electricity production.. In parallel, they also hope to develop a system that will allow them to charge multiple devices at the same time, which is very important if you want to scale this type of wireless charging system.
