1. In theory, wireless charging technology has no harm to human security. The resonance principle of wireless charging is magnetic resonance, which is transmitted only between coils that resonate at the same frequency, while other devices cannot accept bands. In addition, the magnetic field used by the wireless charging technology itself is harmless to the human body. But, after all, wireless charging is a new type of charging technology, and many people are concerned that the wireless charging technology is just as Wi-Fi and mobile antenna poles have just appeared, but the technology itself is harmless.
2. The wireless charging technology uses magnetic resonance to transmit electric energy in the electric field and magnetic field between the charger and the equipment, and the coil and the capacitor form resonance between the charger and the equipment.
