Mi Air Charge can recharge your devices at a distance of several meters

Xiaomi has taken the goal of remote recharging of all of our smart devices one step closer today. The Mi Air Charge can charge batteries at a distance of several meters. This isn’t science fiction; it’s the year 2022!

To begin with, the gadget will only be compatible with cell phones. It will eventually work with smartwatches, fitness trackers, and other smart devices. The ultimate goal is to go wireless throughout the house. Don’t bother with charging connections, stands, or even charging the device itself. Your device will be charged as long as it is in close proximity to Mi Air Charge.

What is the mechanism behind it?

The revelation was posted on the Chinese IT giant’s blog earlier today. Everything sounds incredibly futuristic. Xiaomi defines the technology in this way.

“The five-phase interference antennae integrated into Xiaomi’s self-developed isolated charging pile can correctly detect the location of the smartphone.” “Through beamforming, a phase control array of 144 antennas transmits millimeter-wide waves straight to the phone.”

On the receiving end, comparable technology is required for this to work. A tiny antenna array with a “built-in beacon antenna and receiving antenna array” is included in compatible smartphones. The first communicates information about its location. The second is made up of 14 small antennas that transform millimeter wave signals into electrical energy. This is accomplished using a circuit known as the rectifier circuit.

Your devices can be recharged at a distance of several meters

The Mi Air Charge can currently charge at a rate of 5 watts from a distance of several meters. Only one smartphone can be used at a time for this. The idea is to make it such that it may be used on several devices at the same time.

There’s no need to alter your furnishings. Even physical obstructions, according to Xiaomi, have no effect on charging efficiency.

This is a crucial beginning point for demonstrating the notion. The dream is that one of them will soon be in our living rooms. They will then power all of our smart devices, such as wearables, smart speakers, desk lamps, and more.
