通过电磁场有限元分析软件FEMlab3.3建立了体导电能量传递模型，设计了3种不同形状的电极以优化电极皮肤接触阻抗来提高充电电流传递效率，所采用的Ag电极具有稳定的电极电解质界面,成本低,可重复使用。通过在体外电极上施加不同等级电压以得到最终结果。根据仿真结果，在保证人体安全电流情况下，体导电电流传递效率可达20%以上，能量传递效率在4%~9%之间，不仅远大于无铁芯电磁感应能量传递效率，而且可以进一步实现体内电池体积小型化。
FEMlab3.3(Finite Element Model Lab) is used to develop an energy delivery model for implanted devices. We designed three different shape electrodes made of Ag to enhance current transmitting efficiency. Several voltages were used for pursuing perfect goal. With the body safety current, we can get the results with a current transmitting efficiency of 20% and the energy delivery efficiency of 4%~9%. It is clear that the high energy delivery efficiency can be obtained and the results provide references for further study of energy delivery through body conduction.
