Design and implementation of multi-parameter portable 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 BMD101, TGAM module, 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 the relative deviation is not more than 2% by contrasting with professional instruments. Therefore, the system has promising prospects for household applications.
