利用生物皮肤的电特性,通过皮肤对体内植入式医学电子器件的电池进行充电展开研究.采用有限元法建立体导电能量传递数学模型,通过软件FEMlab 3.3建立其场域数值模型,输入信号使用交流电压.在仿真中,进行了模型的频率特性测试,设计了4种不同形状的电极,并以圆柱形电极为例,分别改变电极截面面积和电极之间的距离来优化电极的形状与布局.仿真结果表明,在保证人体安全电流的前提下,体导电电流传递效率可达30%以上.
It is studied how to charge the battery of the implanted medical device through the skin according to its bioelectrical characteristics.Energy delivery model of volume conduction is created by FEMlab 3.3 (Finite Element Model Lab),using AC voltage as the input.In simulation,the frequency characteristic of the model is tested,and then 4 different shapes of electrodes are designed.Taking cylindrical electrode for example,the shape and layout of electrode are optimized by changing the electrodes’ crosssection areas and the distance between the electrodes.According to the simulation results,current transmitting efficiency can reach above 30% under the premise of ensuring human security.
