低频电流下人体阻抗特性的研究

The Study of Characteristic of Human Body Impedance in Low Frequency Current

目的探讨在低频电流(f<1000Hz)下人体阻抗的的特性。方法采用串联电路法测量94名男性和122名女性在不同频率电流下的人体手臂阻抗的大小。结果随着电流频率的增加,人体阻抗呈现下降的趋势;同等频率下,人体阻抗男性略大于女性。结论人体阻抗具有容抗的特点;皮肤阻抗远大于皮肤下其他组织阻抗。

Objective To discuss the nature of the human body Impedance under the low-frequency current（f1000Hz）.Methods Measure the size of the arm impedance of 94 men and 122 women under different frequency current with Series circuit.Results With the current frequency increase,a downward trend appears in the human body impedance;At the same frequency,the male body impedance is slightly greater than the female.Conclusion The human body impedance has a nature of the capacitance;The skin impedance is much larger than the other organizations under the skin impedance.
