1. Theoretically speaking, wireless charging technology is not harmful to human body safety. The resonance principle used for wireless charging is magnetic resonance, which is transmitted only between coils that resonate at the same frequency, while other devices cannot receive bands. In addition, wireless charging technology The magnetic field used is itself harmless to the human body. However, wireless charging technology is a new type of charging technology. After taking advantage of the wireless source charger from Maiyuan Technology, many people are worried that wireless charging technology will be the same as Wi-Fi and mobile antenna masts. In fact, the technology itself is harmless. .

2. Wireless charging technology uses magnetic resonance to transmit electrical energy between the charger and the device in the electric and magnetic fields. The coil and capacitor form resonance between the charger and the device.

3, this system can be widely used in the future, such as the charging area for electric vehicles and the power transmission for the computer chip. The charging system developed using this technology requires only one hundred and fifty-fifth of the current charging time.

4. The conversion rate has always been a concern for many people. MIT showed that the wireless charging technology has a lower loss than wired charging technology. The wireless charging conversion rate is a few percentage points higher than that of cable. High transformation is also a key factor in the application of wireless chargers worldwide. However, the wireless charging technology is also limited by the distance. In the future, it will be necessary to solve the problem of the long-distance transmission for the precise positioning of the band and the magnetic field.

5. The core chip is one of the difficulties in the application of wireless charging technology. Accurate radiation range control, magnetic field frequency, other controls are all implemented by the chip.
