At present, electronic systems drive various components to cooperatively work by taking electric energy as power, so that the electronic systems can work according to expected requirements of people, and therefore, power supply is one of important factors influencing the development of the electronic systems.

At present, three power supply modes, namely battery power supply, wired power supply and wireless power supply, are generally adopted for power supply of electronic systems. For battery power, the limited energy density and high cost of batteries have been key factors limiting battery development. In addition, since the material for manufacturing the battery contains heavy metals, the leaked heavy metals have a great influence on the environment after the battery is used up. At the same time, recycling of the batteries is also difficult. For wired power supply, when the electric wire is used, the arrangement of the electric wire can affect the placement of a power supply and an electronic system, and the influence of the electric wire on the power supply and the electronic system needs to be avoided as much as possible. In addition, a plurality of important potential safety hazards exist when the electric wires are used, for example, the electric wires are not arranged properly, so that workers fall down when walking, and important safety accidents are caused; the damage of the electric wire caused by the ineffectiveness can also cause electric leakage and electric shock injury. And for wireless power supply, the method has great advantages compared with the two methods. First, wireless power supply is not affected by the location between the power source and the electronic system; secondly, no electric wire is used for power transmission, so that a series of safety accidents caused by negligence of workers are avoided; thirdly, the maintenance cost is low, and the use is more convenient.
