Air Charging

As we saw with Xiaomi's current air charging transmitters, the biggest challenges are the large size of the antenna array used, the high specification and the cost.
When charging, you don't need to connect your Android or iPhone to a wireless charger, but you can. As soon as you enter a room with a base station, your Qi-enabled technology like a phone, smart watch or earbuds starts charging. A Qi charger needs to have a direct connection to your device to work.
According to Xiaomi, the remote charging technology can charge multiple devices at once and charge a smartphone via a walkable path. Xiaomi's wireless charging technology is capable of remotely charging a single device with up to 5 Watts within a radius of several meters. By charging multiple devices at the same time you can enter the game to go any way without connecting to ties.
The WattUp charging technology ensures 2W power transmission between four devices at a charging distance of 4.5 meters and a time consumption of half that of conventional charging charges.
In conjunction with the wireless charging technology of Energouss WattUp, Vivo phones can charge the battery using radio frequency. The technology uses radio waves to wirelessly charge over medium distances, allowing users to charge their smartphones while sitting at a charging station. If it works as Motorola gurus hope it will eliminate the trouble of charging with a dock or cable, charge the device as it goes through the room, and then charge the device at the station by radiating electricity to the device.
Your phone is not tied to a cable or held to a pad - it is not forced to sit or stand on it. Wir have heard about wireless charging for years, but it always reaches its limits. With the current wireless charging technology, below the Qi standard at least, there is room to narrow the gap between the charging coils.
The new Mi Air - charging technology introduced today uses smart room positioning and energy transmission to charge your electronic devices wirelessly. There is no need to place your electronic device on a wireless charger and connect it to a cable. Instead the air charging system works by way of a series of sensors which charge the base station directly on the phone.
The company has not yet agreed to release devices that support Mi Air charging, so we hesitate to lend it too much credence because of this tweet.
The company, called GURU, builds wireless charging systems that relay electricity using high-frequency radio waves, in particular millimeter-wave variant (mmWave) that is underpining the growing 5G cellular networks in the United States.
Next week, the company will reveal three prototypes of the chargers it plans to develop in collaboration with electronics manufacturers at the CES and gave an early glimpse of the technology and explained how it works. Prototypes include a desk-top charging system that can charge devices a few feet away, a floor-to-ceiling version that is the size of a ceiling tile, but has more range, and a Roomba-like robot that can move around large spaces to charge small smart-home devices such as cameras and IoT sensors. Chinese smartphone maker Xiaomi has also emphasized wireless charging technology for the air.
Earlier in the year, Xiaomi showed a concept video of a charging phone in an airspace. Motorola says it will give 5 watts of power to charge a phone which is not enough to fully charge a phone.
Around the same time Lenovo's Motorola launched its own air-carrying technology. Motorola has also partnered with Guru Wireless, a company that works on multi-device air charging solutions. Motorola recently announced that it is exploring a wireless long distance charger solution for future generations of its products.
The majority of mobile phone manufacturers have accepted Qi wireless charging as an important factor in their designs, and widespread use of wireless chargers and devices for Android and iPhone shows the popularity of the technology. According to Xiaomi's official vision the core of air charging technology of the company lies in positioning in space and transferring air energy. In the near future, the company will develop its own space-isolated charging technology that can work with smart watches, wristbands and other wearable devices.
Tech company Ossia, which has been working on true wireless charging over the air in recent years, revealed at CES 2019 that it has partnered with mobile phone accessory maker Spigen to develop the first true wireless charging case. BEIJING, China, January 29, 2021 -- Global technology leader Xiaomi introduced a new form of charging today, the charging technology of Mi Air. Mi Air revolutionizes current wireless charging methods and allows users to charge electronic devices wirelessly with a wireless charging stand.
The ability to send electricity from one place to another through the air is not a new idea, but it has been occupying engineers for many years because it requires wires. A number of companies work on air charging, including Pasadena-based Guru Wireless, a start-up that developed a series of innovative prototypes capable of transmitting power without cables.
Founded by a team of Caltech engineers and scientists, mmWave uses proprietary 2.4GHz RF lens technology to transmit electricity through air at distances of three feet or more enabling multiple devices to be charged simultaneously. The company showed its technology earlier this year at CES to show how it can be used to charge devices such as smartphones and IoT devices.
so do you think that air charging is the future. Let me know in the comments.
