Wireless charging black technology reproduces rivers and lakes

In recent years, wireless charging has become a hot spot, and along with the introduction of various wireless charging products, but it has not really reached the ideal wireless charging. Recently, the University of Washington invented the "laser charging method". This charging beam can provide a stable power output within a range of 4.3 meters.

The concept of "wireless charging" is a breakthrough in the charging method of mobile phones in recent years, but the current wireless charging technology still needs to place the mobile phone on the charging base. Although there is no line to connect, there are still some restrictions on use. Not really "wireless".

According to reports, the University of Washington has invented a "laser wireless charging method", which is to directly charge the charge to the mobile phone for charging by using a safe invisible laser beam. It is reported that the speed is equivalent to the USB cable , even if it is separated. 4 meters is also no problem at all.

It is understood that this innovative charging method produces a focused beam in the near-infrared spectrum, and then emits a charging beam through a laser emitter to transfer the charge to a thin battery on the back of the phone.

It is reported that this charging beam can provide a stable 2W power output within a range of 4.3 meters.

In the people's mind, the laser beam is dangerous, but the research team said that they don't have to worry about it. They have specially designed it. For example, in order to release more heat in the charging beam, they set a special purpose. The heat sink is surrounded by a low-power, harmless protective beam, and the laser is automatically cut off when there is a human desire to cross the beam.

If this technology can really be realized, it will not only charge the smart phone, but also bring good news to other digital devices, making troublesome wires and sockets a thing of the past.
