一种便携式生物电阻抗测量装置的设计与验证
Design and validation of a portable bioelectrical impedance measurement device
摘要
Abstract
Addressing the problem of bulky size,high power consumption and high cost associated with traditional bioelectrical im-pedance detection devices,we designed a portable,low-cost and single-channel bioelectrical impedance measurement device.Firstly,this device centered around the AD5933 impedance conversion chip,integrated various functions such as wired data transmission,wire-less communication,and real-time local data display.It could perform single-frequency and multi-frequency scanning of bioimpedance spectra within the frequency range of 2～100 kHz,achieving impedance monitoring and impedance spectrum analysis.Finally,we con-ducted experiments on the measurement accuracy of the three components,and the consistency of human body electrical impedance measurement respectively.The results showed that the impedance measurement error of this device within the frequency range of 2～100 kHz was less than 0.6%,with small size,light weight and low power consumption.It could meet the clinical requirements for dynamic monitoring of human body impedance.This research can provide a new solution for the monitoring and evaluation of non-invasive physi-ological signals.关键词
