Android-based Mobile Application for Home-based Electrocardiogram Monitoring Device with Google Technology and Bluetooth Wireless Communication

Cardiovascular disease (CVD) is a heart related disease and is remained as top silent killer in worldwide. Frequent electrocardiogram (ECG) monitoring for patients with CVD is vital to check if arrhythmia occurs. Though there is a lot of commercialized portable heart screening device, most of them are not integrated with Internet of Things (IoT) technology, lack of user-friendly interface and data management system. This paper presents a mobile application development for in-house designed home-based heart screening device which integrates with Google technology and wireless Bluetooth communication. ECG acquisition hardware communicates with developed mobile application using wireless Bluetooth technology to enhance the product mobility and less wiring for user convenience. The acquired ECG data is real-time displayed in mobile application and stored in external file storage for further post-processing. By using Firebase Authentication and Firebase Storage provided by Google technology, it allows admin to have full control on database management. The location service is also enabled, to allow user to notify others about their current location if there is any abnormality detected in user, for any necessary prompt medical action. In short, this mobile application allows wireless data communication using Bluetooth, real-time display of ECG graph, external ECG data storage and data uploading to cloud storage for post-processing, online data management system with user authentication, location detection and abnormalities detection.
