Design of bio-impedance body composition tester based on four-electrode multi-frequency scanning
摘要
Abstract
Bioimpedance contains abundant human pathology and physiological electrical signals,which can be used as the main basis for medical personnel to accurately judge patients and treat diseases.On this basis,a multi-parameter measurement system for human body based on Cole-Cole theory is proposed.In the system,a human body impedance model is constructed to collect and analyze various body parameters of the human body by means of carbon nanomaterial electrodes.The low-frequency signal injected into the human body is generated by means of the signal generation circuit,the amplitude detection circuit is used to detect the voltage generated by the current flowing through the human body,and the segmented detection method is used to measure the impedance information of different segments of the human body.The signal is input into the RT1052 microprocessor by means of the amplification circuit to analyze the correlation between the data and human body composition parameters,so as to obtain various human body composition parameters,and display the measurement results.After testing and analysis of the system,it is found that the designed system can accurately measure parameters such as human protein and fat,with an error range controlled within 5%,and has good application prospects.关键词
