Tech company Xiaomi has introduced the Mi Air Charge technology. According to the company “remote charging technology” can charge multiple devices simultaneously and will recharge a smartphone that’s being used, “while walking around or even when something’s in the way”.
In a blog post shared by the company, it has outlined how the technology works. The transmitter is quite large, almost like a side-table next to a couch, and can provide a 5W charge wirelessly to a smartphone.
The company’s self-developed isolated charging pile has five phase interference antennas built in, which can accurately detect the location of the smartphone. A phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming.
This kind of charging has nothing to do with the Qi standard. The smartphones need to be outfitted with a “miniaturized antenna array with built-in ‘beacon antenna’ and ‘receiving antenna array’.” The smartphone has 14 antennas to convert a millimeter wave signal that’s emitted by the charging pile. The signal is converted into electric energy through a rectifier circuit.
As of now, Xiaomi’s remote charging technology claims to charge multiple devices with a 5W current within a radius of “several meters”. Xiaomi also claims that physical objects don’t reduce the charging efficiency. The company has said that the Mi Air Charge tech could be eventually compatible with smartwatches, fitness bands, and other wearables as well.
As of now, no release date has been offered for the Mi Air Charge system, and it’s not known if such technology would ever make it to the consumer market either.
