Problems solved by technology

The current basis of wireless energy transmission is the near-field mutual induction coupling theory, but the traditional mutual induction coupling structure has the disadvantage that the transmission efficiency decreases rapidly with the increase of distance, and the received and recovered power energy fluctuates obviously with the distance, which is easy to cau
