One innovation we won't be seeing anytime soon: Over-the-air charging.

Several companies have demonstrated over-the-air charging of slot xo smartphones, but none have tried to sell them.Consumer electronics companies are dreaming of a future where wires and wireless charging surfaces are obsolete.They dream of a time when the charging will come out like this: you walk into the room and your smartphones and other small devices will automatically start to receive air power from nearby transmitters. Nearby, perhaps embedded in a ceiling lamp or plugged Under the desk like a Wi-Fi router For at least five years the companies promised we were almost there. And in the choreography demonstrations, some people have also shown that phones can be charged over-the-air.

But we have not yet reached There is no charger on the market for remotely powering the smartphones. And it is unclear whether there will be one or not.There is no debate. For the conscious, over-the-air charging is a dream. It will be the most incredible experience, ”said Jake Slatnick, chief executive officer of wireless charging technology company Aira. Make it something practical That doesn't stop some people's efforts. Since its inception, at least four companies have launched an over-the-air charging concept.Last month, Chinese smartphone company Oppo introduced “air charging without cables or a charger” in a video demonstrating the company's smartphone concept with an expandable display. It seems to keep charging after being lifted from the pad.

In January, consumer electronics giant Xiaomi mocked the Mi Air Charge, which in the video looks like a huge white power box that represents the "true wireless charging era." Called "Motorola One Hyper", Aeterlink in Tokyo announced "Airplug", which claims it can power the device up to 65 feet away.These three companies have garnered some media attention, although each says they have no plans to bring a product to the market for smartphones.Others have completely abandoned the over-the-air charging scheme, some researchers. People in the field have questioned whether people will ever see remote charging vision as an effect.Companies looking to install over-the-air charging hubs face a number of challenges, the most striking of which is physics. The further it is from the direct power source,

the lower the charging efficiency. So even if your phone receives power at a distance But it might not be a meaningful number.
There is also a Federal Communications Commission recommendation that limits the amount of radio frequency energy that can flow through the air in your home. Too much can interfere with other gadgets or lead to various health problems.Companies looking to introduce air charging to the world are also facing an uphill battle with Qi, a globally recognized wireless charging standard. The protocol allows the charger to emit 15 watts of wireless power so that Apple, Samsung, Huawei, etc. devices can run slowly when placed on the dock. Still, today's wireless charging hubs are far from. Perfection makes room for innovation to tackle these shortcomings.For example, if your phone isn't perfectly aligned on the charger, it won't work.Apple canceled plans for the AirPower base in 2019 for that reason. real

That makes the idea of over-the-air charging so compelling.Companies are looking for ways to make the smartphone charging process more convenient, so your phone doesn't have to be near an outlet or on a base. Strategically charge One idea is a remote wireless charger that screws into the light bulb socket. It is a product sponsored by the Israeli company Wi-Charge, which uses infrared light to transmit two watts of power, enough to be in the safety realm.The company showed off the technology at the year's CES global technology conference. 2020 and won an innovation award for long-range charging capability.But bringing that technology to a smartphone "will take at least a few years," according to Wi-Charge co-founder Ori Mor.

Mor's idea is that the transmitter plugs into a traditional power supply around the house and converts electricity into an infrared laser beam. A receiver embedded in a smartphone converts that light into energy. But to work, smartphone makers will have to integrate this technology with chargers and phones, space companies say it could happen. But the smartphone product cycle usually takes two years, so deployment is still several years.It's unclear how big the need for over-the-air charging is. Most people seem to be fine with Qi-enabled smartphones.The standard fueled growth in the overall wireless charging market, which is worth $ 4.5 billion, according to some estimates.For now, Wi-Charge is focusing on commerce and is using remote charging technology to power security cameras and smart shelves in U.S. retail stores. The first application around the house will help make it smart.
