A method for multiple-transmitter-multiple-receiver wireless power and signal transmission based on inductive coupling

In order to facilitate the wireless power and signals transmission in scenarios involving multiple receiving devices, this study introduces a method for such transmission. This method, which is based on the principle of inductive coupling, is designed for use with multiple transmitters and receivers. A signal transmission coupling mechanism is incorporated into the existing energy transmission structure. The system's energy transmission topology is based on the LCC-S composite resonant network topology. Digital signals are modulated and demodulated using the binary amplitude modulation (2ASK) method, which allows the data stream being transmitted to be modulated to the appropriate carrier frequency band for data transmission. The feasibility and effectiveness of the proposed method are ultimately confirmed through experimentation.
