Cardiovascular diseases are the leading cause of mortality worldwide according to the world health organization. Electrocardiogram (ECG) test is used to detect these life-threatening diseases. It records the electrical activity of the heart and provides information about heart rate, rhythm, and shows if there is enlargement of the heart due to high blood pressure or a previous heart attack . Traditional ECG monitoring devices require skin preparation that includes cleaning the area, shaving the chest hair and applying conductive gel on skin. Wires are needed to connect the electrodes to the monitors, which makes the patient uncomfortable. They are also not ideal for remote or continuous heart monitoring since they are mostly done in hospitals and clinics. A flexible, portable, and wireless ECG monitoring device was developed to solve these issues. The device consists of dry electrode sensors, a comfortable chest belt, and a flexible printed circuit board capable of processing and transmitting the ECG signal to a mobile application on an android smartphone. The dry electrodes on the chest belt are able to detect the ECG signal without any skin preparation. The detected signals are transmitted via Bluetooth to a mobile application for display. The project aims at making ECG tests accessible and affordable to everyone. This paper explains the process that took place to build our ECG monitoring device and its excellent performance in comparison to a traditional ECG test.
