Abstract

This master's thesis deals with the development of wireless portable one channel ECG device. The ECG measurement is carried out on the test person using the AD8233 biosignal amplifer, for which a customised Printed Circuit Board (PCB) was developed. The acquired ECG signal is sampled by an ESP32 microcontroller, which also acts as an access point. At a fixed sampling rate of 250 Hz, the ECG signal is recorded and sent to a second ESP32 microcontroller via a WLAN connection. This microcontroller acts as a client, continuously receiving the ECG signal and forwarding it to a computer via the serial interface. A developed Matlab-GUI allows the user to view the ECG signal in real time. A housing was developed and 3D printed for the ESP32, which acts as an access point, the AD8233-PCB and the power supply for the two components. The housing allows the electronic components to be attached and can be fastened to a waistband using a clip.
