摘要

本文介绍了一种基于AD5933电路的阻抗测量系统。阻抗测量范围为9 Ω至18 MΩ，频率范围为1khz ÷ 100khz。本文还提出了扩大这一测量范围的可能性。系统自动校准，阻抗模量测量的相对误差在±2%范围内。测量的阻抗主要参数在OLED显示器上显示，但也可以存储在SD存储卡中以供进一步处理。该系统具有可移植性、模块化和适应性强等特点。

Wearable impedance analyzer based on AD5933

In this paper a system for measuring impedance, based on AD5933 circuit is presented. The impedance measuring range is between 9 Ω and 18 MΩ for a 1 kHz ÷ 100 kHz frequency range. Possibilities of expanding this range of measurement are also presented in the paper. The system calibration is automatic and the relative error of the impedance modulus measurement is in the range ±2%. Measured impedance main parameters are shown locally on an OLED display but can also be stored in an SD memory card for further processing. The system is portable, modular and adaptable to a large number of applications.
