Development History Of Wireless Charger

- Jan 27, 2018 -

As early as the 1830s, Michael Faraday found that changes in the surrounding magnetic field would generate electricity in the wire. In the the 1890s, Nikola, a Serbian-born scientist, applied for an initial patent.

Unfortunately, this research has been delayed for a century. The biggest hurdle is inefficient transmission and danger. Electromagnetic radiation is only suitable for transmitting information and is not suitable for transmitting energy. Because the radiation is not directional, energy will be wasted in useless space. Some people envision the use of directional electromagnetic radiation, such as laser, but its operability is not strong and extremely dangerous.

Professor Xu Shuyuan, Department of Electronic Engineering, City University of Hong Kong, has successfully developed a "radio pool charging platform" in the early years, which can put several electronic products on a charging platform, without the need of external wires, automatic charging through low-frequency electromagnetic fields, charging time is no different from the traditional charger. But this technology still needs the product and the charger contact, it mainly uses the near field electromagnetic coupling principle.

Researchers at MIT in the United States have made new advances in wireless power transmission, using a power supply two meters away, with a 60-watt light bulb lit by a "separate ground".

Soliacic design, the wireless energy transmission of the radiation has a distance limitation, the smaller the receiver the shorter the distance. He calculates that the size of a laptop can receive wireless energy over a few meters, "so that installing a source in each room will power the entire home laptop."
