In 1890, physicist and electrical engineer Nikola Tesla (NikolaTesla) has already done a wireless transmission test. The International System of Units of Magnetic Induction is also named after him. The wireless transmission method conceived by Tesla is to use the earth as the inner conductor and the earth's ionosphere as the outer conductor, and establish a low-frequency resonance of about 8 Hz between the earth and the ionosphere by amplifying the transmitter in a radial electromagnetic wave...
New electronic products, especially portable electronic products such as digital cameras, mobile phones, tablet computers, etc. are more and more used in people's work and life, and the matching chargers also use traditional wired chargers. The compatibility and versatility of the wired charger are relatively poor, and it is inconvenient for users to carry and charge. At the same time, post-disposal treatment increases environmental pollution. Therefore, it is urgent to provide users with more...
