In this paper, we will discuss the innovations of electromagnetic induction technology in wireless power and transmission, and its impact on the future energy sector.

1.Innovations of electromagnetic induction technology in wireless power transmission:

Resonant magnetic coupling wireless charging technology: through the principle of resonant magnetic coupling, the electromagnetic field at the transmitting end is coupled with the resonator at the receiving end to achieve wireless charging of mobile devices. This technology enables efficient, long-distance wireless charging, and is used in smartphones, electric vehicles, and other fields.

Long-distance wireless power transmission technology: Using the principle of electromagnetic induction and designing an efficient electromagnetic field transmitting and receiving system, wireless power transmission over a few metres to tens of metres or even longer distances can be achieved. This technology can be used for wireless charging station and wireless power supply system in the city, etc., which can bring more convenient energy service for city life.

2.The innovation of electromagnetic induction technology in wireless energy transmission:

Microwave power transmission technology: generate microwave energy through the transmitting end, and transmit it to the receiving end for energy conversion through electromagnetic waves to achieve wireless energy transmission. This technology can be used for long-distance energy transmission, such as space solar power station to the earth to transmit energy.

Laser power transmission technology: the use of laser beams to transmit energy from the transmitting end to the receiving end, and through the photoelectric converter will be converted into electrical energy. This technology is characterised by high efficiency and high precision, and is suitable for scenarios requiring high energy density and long-distance transmission.

3. Impact brought by innovation and future outlook:

Improve the efficiency of energy use: the innovation of electromagnetic induction technology makes energy transmission more efficient, reduces the loss of energy in the transmission process, and improves the efficiency of energy use.

Promoting energy transition and sustainable development: innovations in wireless power and energy transmission technologies help promote energy transition, reduce dependence on traditional fossil energy sources, and promote the development and utilisation of renewable energy sources.
