Design of an eight-electrode human body impedance spectrum measurement system
Year: 2025
Type: conference-paper
Abstract: Due to the selective permeability of the human cell membrane, the impedance of the body changes significantly at different frequencies. After cells undergo carcinogenic, changes in their composition and structure cause their impedance to differ from that of normal cells. This paper designs an eight-electrode impedance measurement system based on the AD5933 measurement chip and the STM32F103ZET6 microcontroller chip. By analyzing and processing data from four groups of eight channels, the system can accurately measure the impedance values of the human body at different frequencies and plot the impedance spectrum. The trend of the impedance spectrum can reflect the health condition of the human body to some extent. Through the analysis of the measurement data, the system demonstrates low measurement error and strong stability, meeting the design requirements. In the future, this system could be applied to the early prevention and detection of breast cancer.
