The Chinese gadget company Xiaomi is bringing a new device for wireless charging, and truly it is according to the name, Mi Air Charge, it allows multiple devices to be charged with 5W power. It differs from the already existing technique where devices only within a specific distance of four centimeters are charged, the widely known Qi standard. This new device will charge many devices simultaneously, even with physical barriers, which means things placed between the charging pile and devices won’t hamper charging, placed within a “radius of several meters.”
Technical Features Of The Device
The device is equipped with an isolated charging pile unit with five phase interference antennas for detecting the location of the devices to be charged. There are 144 antennas in the phase control array for direct transmission of the mm-wide wave to the device through beamforming.
However, there are specific hardware conditions to be met by the smartphones to be charged. A “beacon antenna” and “receiving antenna array” has been built in Xiaomi. According to the makers, the former will broadcast position information with low power consumption, while the latter will be composed of 14 antennas, which will convert the mm-wave signal given off by the charging pile to electric energy with the help of the rectifier circuit.
Xiaomi aims at extending the charging to other gadgets like smartwatches, wristbands, and other wearables. Even smart home speakers, desk lamps, and more in the future. The makers elaborately said that in the coming days, our lamps, speakers, small home products would get powered wirelessly, making our houses and lives free of them.
It’s important to note that the technology of the Mi Air Charge device is only a demo and not immediately getting launched to consumer products this year. They have not yet released any regulatory guidelines or health risks associated with its development.
This new device just indicates that tech houses are putting importance on developing the most advanced and latest wireless charging technology each passing day.
Like Xiaomi, Motorola uses a wireless charging technique where a device within a meter can be charged. Apple is also continuing their research on newer technologies of wireless charging, just like the latest Magsafe in iPhone 12 model. Stay tuned for more updates.
