Project Objective

In this project, I construted a multi-modal physiological signal acquisition system to collect and display mutiple human physiological data, including ECG, PPG, dual-channel EEG and dermal resistance.

System Architecture

As the Fig. 2 shown, the receiving end consists of a PC and 1 BLE master to receive 4 BLE slaves at the same time.

Fig. 2 One master device receives data from 4 slave devices.
