基于AD5933阻抗测量芯片的人体经穴阻抗动态监测系统研制
Development of AD5933-based human body meridian impedance dynamic testing system
摘要
Abstract
Objective:To design the human body Meridian impedance dynamic testing system, to make clear the response of the human body Meridian impedance in the low frequency range. Methods: The system uses STM32F103RBT6 as a controller to read and write AD5933 internal registers in order to control the impedance measurement. Outer join ADG711 analog switch in order to achieve different range. Select SGM4782 as dual analog switch to strobe A,B two channels. Join in the constant current source based on AD844 between AD5933's Vout feet and Vin feet. Sample data is read into the PC via SD card.Results: The system can reflect the real-time impedance values and impedance curve under the sweep excitation from 1kHz to 128 kHz.Conclusion: The human body meridian dynamic impedance detection system based on AD5933 can accurately reflect meridian impedance information, and it can also be as a research tool to further defined meridian impedance characteristics.关键词
