体导电能量传递二端口网络集总参数的计算
摘要
Abstract
Skin electrode unit is a channel through which energy can be transferred to the implanted device by volume conduction.The unit can be equivalent to lumped circuit,but so far there are no appropriate calculation methods of these circuit parameters,so variable load method based on field-circuit coupled is proposed.A skin electrode unit field circuit coupled model is established to obtain the relationship of the network parameters between voltage and current at electrode port,and the amplitude and phase of the power signal is extracted by the use of all phase FFT spectrum analysis.On this basis,equivalent circuit impedance parameters of the skin electrode unit under various conditions are obtained by the application of variable load method and the validity of the method is verified.As a result,the equivalent circuit impedance parameters obtained in this way can be used for the circuit analysis and optimization of the volume conduction energy transfer system.关键词
