摘要

介绍了一种多频便携式人体阻抗测量系统，该系统可用于人体全身和节段阻抗测量。数字信号处理器是将交流电注入人体的测量系统的核心，也是检测和分析交流电注入后产生的电压的核心。生物阻抗测量采用四极电极装置。生物阻抗测量是在18千赫到576千赫的对数频率范围内进行的。阻抗幅值和相位在全身和节段生物阻抗测量中表现出相似的趋势。

Multi-frequency and multi-segment bio-impedance measurement using tetra-polar electrode setup

A multi-frequency portable bio-impedance measurement system used for whole human body and segmental body impedance measurements is presented in this paper. Digital signal processor is the core of the measurement system used for injecting alternating current into human body and also for sensing and analyzing the voltage developed in response to the injected current. Tetra-polar electrode setup is employed for bio-impedance measurement. Bio-impedance measurements are performed at logarithmic frequencies in the range between 18 kHz to 576 kHz. Impedance magnitude and phase show similar trend for whole body and segmental bio-impedance measurements.
