HI FRIENDS,
Xiaomi on announce the Mi Air Charge, A new wireless charging technology.
Mi Air Charge is design to let users remotely charge their electronic devices including smartphones without any cables, pads, or wireless charging stands.
This is not like existing wireless charging technologies like the ones based on the widely adopted Qi standard in which the power transfers wirelessly using inductive charging over a distance of up to four centimetres.
Xiaomi’s Mi Air Charge is claim to charge multiple devices “within a radius of several metres” and even with physical obstacles.
This technology will not become generally available in the near future, and remains in a concept phase.
To enable the new Mi Air Charge wireless charging experience, Xiaomi has develope an in-house isolated charging pile with a phase control array that consists of 144 antennas transmitting millimetre-wide waves.
These waves go directly to the smartphone that requires charging through beamforming.
The charging pile also carries five phase interference antennas to understand the location of the smartphone.
Xiaomi’s Mi Air Charge technology is only being showcase for now, with a Xiaomi spokesperson providing clarity on Twitter.
Xiaomi Spokesperson Said :
The Mi Air Charge is currently a technology demo and is not coming to any consumer products this year.
It is currently unclear whether Xiaomi has applied for any regulatory approvals for the new wireless charging technology.
The company has also not provided any details on whether its development has been tested for health risks. We’ve reached out for more details in near future.
As Xiaomi is using a proprietary technology infrastructure, the smartphones that can work with Mi Air Charge will require an antenna array with a built-in beacon antenna and receiving antenna array.
Xiaomi Said in a blog :
“Beacon antenna broadcasts position information with low power consumption.
The receiving antenna array composed of 14 antennas converts the millimetre wave signal emitted by the charging pile into electric energy through the rectifier circuit, to turn the sci-fi charging experience into reality,”
The initial model of Mi Air Charge technology is said to be capable of delivering 5W remote charging for a single device within a radius of several metres.
Xiaomi claims that multiple devices can also be simultaneously charge with each of them supporting 5W using the same technology.
Tech gient Xiaomi has demonstrated the new technology for smartphones, though it mentioned that it would work with smart watches, bracelets, and other wearables in the near future.
Xiaomi Said :
“Soon our living room devices, including speakers, desk lamps and other small smart home products, will all be built upon a wireless power supply design, completely free of wires, making our living rooms truly wireless,”
