摘要
针对人体阻抗的分段变化、受频率影响的特征,采用多频多段的阻抗测量方法来测量人体阻抗。同时,利用嵌入式系统开发的技术优势,设计基于ARM-Linux的便携式人体阻抗分析仪,并分析了该仪器的硬件设计与软件设计。最后,对测量数据进行了分析,结果表明分析仪的方案可行。
Human impedance has the character that the different parts have different values, and it is also affected by the frequency of the exciting signal.So the multi-frequency and multi-segment method is adopted to measure the human impedance.Meanwhile, taking advantage of the technology of embedded systems, the hardware and the software of the portable human impedance analyzer are designed.Finally, measurement data is analyzed, and the results indicate that the scheme of the portable human impedance analyzer is feasible.
