Abstract

The research on implantable ultrasonic coupling wireless power transmission systems has not been systematically analyzed from the sound field theory, and the influencing factors of implanted ultrasonic coupling wireless power transmission systems based on the far-field model are proposed in this paper. Firstly, the far-field model is constructed. On this basis, the main factors affecting the ultrasonic energy transmission in the system are discussed. The COMSOL finite element simulation software was used to simulate the ultrasonic coupling wireless energy transmission system in human tissue environment, and the directivity of the energy transmission system was verified. The system experiment platform is built to analyze the energy transmission under different distances, different sound source frequencies and different sound source excitations, and compare with the numerical simulation data. Finally, the influence of different factors on the energy transmission system is verified. It provides an effective reference for further research on implantable ultrasonic coupling wireless power transmission systems.
