低频电流下人体阻抗模型的研究

Study on model of human body impedance under the low-frequency current

目的:探讨低频电流(f<1000Hz)下人体阻抗的模型。方法:采用串联电路法测量94名男性在不同频率电流下人体手臂阻抗的大小。结果:随着电流频率的增加,人体阻抗呈现下降趋势。结论:人体阻抗模型可以认为是由电阻和电容组成的复杂的串并联电路,因而具有容抗的性质。

Objective： To discuss the model of the human body impedance urLder the low-frequency current （f〈1 000 Hz）. Methods： The size of the arm impedance of 94 men under different frequency current was measured with series circuit. .Results： With the current frequency increase, a downward trend appeared in the human body impedance. Conclusion： The human body impedance models can be considered to be complex series-parallel circuit composed of the resistors and capacitors, which has a nature of the capacitance.
