Establishment And Optimization Of Human Skin Charge Modeling

Charging the medical implant device is a hot issue, the current commonly used methods are RF telemetry, transmission of light telemetry, ultrasonic transmission, but their common drawback is that the body's ionic body fluids will affect the transmission efficiency, resulting in energy transmission reliability to reduce. This paper presents a charge model based on human skins, which utilize body's own conductive ability to implement the transfer of energy to the human body implanted electronic devices. This is an innovative way of charging, which is known as the volume conduction transmission. The author uses the classical Maxwell electromagnetic field theory to establish the mathematical model of the volume conduction electromagnetic field. The simulation model of energy transfer based on the volume conduction is established by simulation experiment with COMSOL Multiphysics software, and the input signal frequency, electrode size and electrode shape are compared. The experimental data are analyzed, finally the optimization proposal of the energy transfer efficiency of the bulk is proposed.
