We are very well aware of wired and wireless charging technology but have you ever heard of a technology yet that fuels the devices over the air? Yes, we are talking about the Mi Air Charge, Xiaomi has introduced a new wireless charging tech that is designed to remotely charge electronic devices without any cables or wireless charging stands. The Mi Air Charge Technology can charge multiple devices using inductive charging over a distance of up to four centimeters.
The Chinese smartphone company has announced a new wireless charging tech Mi Air Charge. The charger comes with the ability to wirelessly charge the device over the air. The announcement was made through a blog post which says, “Global technology leader Xiaomi today introduced a brand new form of charging – Mi Air Charge Technology. Revolutionizing the current wireless charging methods, Mi Air Charge Technology enables users to remotely charge electronic devices without any cables or wireless charging stands. Today, we enter a true wireless charging era.”
Xiaomi’s remote charging core technology lies in space positioning and energy transmission. The charger has built-in five-phase interference antennas that are touted to detect the location of the smartphone. The phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming.
According to the company on the smartphone’s side, Xiaomi has also developed a miniaturized antenna array with a built-in “beacon antenna” and “receiving antenna array”. Beacon antenna broadcasts position information with low power consumption. The receiving antenna array composed of 14 antennas converts the millimeter-wave signal emitted by the charging pile into electric energy through the rectifier circuit.
The Mi Air Charger capable of 5-watt remote charging for a single device within a radius of several meters. Apart from that, multiple devices can also be charged at the same time (each device supports 5 watts). As per Xiaomi even physical obstacles do not hamper or reduce the charging efficiency.
