Problems solved by technology

However, whether it is a small electrical appliance or a large electric vehicle, the currently widely used charging and supply method is electromagnetic near-field coupling. The transmitting coil and the receiving coil are close to each other (generally millimeter or centimeter level), which is obviously not suitable for wireless networks with randomly distributed nodes. Sensor Networks

Moreover, wireless charging and power supply equipment for electric vehicles and home appliances generally have high power, and sensor nodes are all low-power electronic devices, so they are not suitable for charging and supplying nodes.

Magnetic resonance wireless charging power supply method is difficult to transmit energy over long distances, and the transmission efficiency decays exponentially with distance

The microwave wireless charging power supply method is greatly affected by environmental factors, and it is difficult to effectively transmit energy
