Although there are many devices that support wireless charging, the charging base must be touched at the moment, and the base needs to be connected, which is still inconvenient to some extent.
Today, Xiaomi officially announced its self-developed air-to-air charging technology, no need to touch the base, no need to use a charging cable, within a radius of several meters, whether the mobile phone is held in the hand or in the pocket, it can be charged.
In the latest picture, Xiaomi also stated that the current charging power is 5 watts, but if there are multiple devices, each device can reach 5 watts, and even foreign objects will not reduce the charging efficiency. The practicality is still quite strong. .
In addition to charging piles, Xiaomi also introduced that they have self-developed a miniaturized design of antenna arrays on the mobile phone, with built-in “beacon antennas” and “receiving antenna arrays.” The beacon antenna broadcasts location information in the space field through 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, realizing the science fiction air-space charging experience.
It is conceivable that in the near future, mobile phones, bracelets, watches and even speakers, desk lamps and other devices that support wireless charging in the living room can enjoy new technological dividends.
