Design of multi-parameter embedded biological information measurement system

In order to overcome the disadvantages of poor portability and insufficient multifunctionality in traditional human health parameter measurement, a portable multi-parameter embedded electroencephalogram (EEG), electrocardiogram (ECG), and bioelectrical impedance (BEI) measuring system based on chip BMD101, the TGAM module, chip AD5933, STM32, and wireless Bluetooth transmission was designed and implemented in order to meet the requirements of accurate measurement. Experimental results show that the system has effective stability for continuous operation, and in contrast to professional instruments, the maximum deviation of electrical impedance measurement is not more than 2%, the deviation of the average heart rate can be confine within a range of ± 2, Therefore, the system has promising prospects for household applications.
