摘　　要：本文设计了一种基于电阻抗原理人体成分分析仪。该分析仪包括上位机、微型打印机、体重测量电路、电极和阻抗测量电路5个部分。通过检测体重和阻抗参数,运用相敏检波的计算原理设计分析仪的软硬件系统。实验评估证实,该分析仪具有较高的测量精度,达到了预期设计标准,可以广泛运用于人体健康检测。A human body composition analyzer was designed in the paper based on the principle of bio- electrical resistance, which consisted of 5 sectors including the upper computer, micro printer, weight measurement circuit, electrodes and the impedance measurement circuit. Through detection of the weight and impedance parameters, the hardware and software system of the analyzer were designed with the adoption of the principle of phase sensitive detection. According to the experimental evaluation, the analyzer proved its high accuracy of measurement and conformity to the intended design standards, which could be widely applied in human health examinations.
