In order to realize the measurement and quantitative analysis of human physiological components,a collection and analysis system is designed according to human body electrical impedance signals,which is based on the AD5933 chip-based extension circuit and PSO-ELM prediction algorithm as the core.It can not only collect and analyze human electrical impedance signals in real time,but also process and analyze them at different frequencies,so as to achieve the intended goal of this program.In this design,the overall debugging of the system is completed and the relevant figures such as the electrical impedance of the human body are collected and processed triumphantly.The analysis results show that the system operates stably,has a high accuracy rate,and meets the expected design requirements.
