Since the invention of the phone, we are using Traditional Wired Method to charge the device. As time passes by, new inventions like Near-field wireless chargers, Wifi chargers and Fast-charging technologies also improve the way we charge our phone.
But it's a pain to plug your phone every time you are running out of juice. Most of the people are accustomed to using the traditional charging method. But it is very inconvenient to charge the phone through the plugged wire or placing it on NFC systems. A big headache? Now there is a solution to this issue. That is laser charging! Your phone will be fully charged within 10-20 milliseconds!
So we need to build a phone case or sticker alike stuff, which had the Laser Light Receiver integrated into it, and then we need to buy the laser setup. It will be a standalone thing, like a Wi-Fi router. In simple words you put your phone down anywhere in a room, the laser finds the phone, and beams its light into the photovoltaic cell, like a solar cell (in reverse). But the downside is one little obstacle which could disconnect this whole process. Other people have used lasers as a way to power stuff as cool as satellites and drones, or to transmit space-harvested solar power back to Earth. But charging a phone? Nah! This incredible invention is from A team of electrical engineers at the University of Washington.[url=https://c.mi.com/forum.php?mod=viewthread&tid=842788&aid=1846270&from=album&page=1" class="orange" style="display: inline; color: rgb(255, 103, 0); text-decoration-line: none;][/url]
Safety is the biggest concern while talking about lasers. And the UW team has thought of your safety. The signal arrives at the speed of light, so it's highly impossible to try out your hand through the outer beam to touch the charging laser.
It will work in a very simple way. The phone to be charged will chirp a few times at a frequency inaudible to human ears. Microphones on the laser emitter pick those up and use time-of-flight to calculate the rough location of the phone, then it sweeps the low-powered guard ring of light until it hits the retroreflectors. When the signal comes back, assuming nobody's eyeball is in the way, the near-IR laser spins up and starts charging. They wanted to be able to deliver roughly 1 watt of power to a receiver just about the size of your pinky fingernail, efficiently enough to charge a device. A near-IR laser capable of delivering the 4.3 watts/ sq.cm that could make the math work would be both invisible and able to damage a human eye in less than 10 microseconds. That's super fast.
