Portable ECG Design for Convenient Use in Public Spaces

Designed with practicality and comfort in mind, heartGO introduces an innovative portable ECG solution tailored to provide flexible and accessible heart monitoring for everyone. Unlike conventional ECG devices that require chest placement—often necessitating users to undress—heartGO only needs to be attached to the right and left index fingers and the left ankle. This not only preserves user privacy but also makes it feasible to use the device in public spaces, offering a hassle-free solution for regular heart check-ups.

Weighing under 200 grams, heartGO is lightweight and highly portable—even small enough to fit in a pocket. It also works offline and features a rechargeable battery, ensuring users can rely on it during emergencies or in areas without internet access.

Despite its compact and practical form, heartGO does not compromise on accuracy. Testing has shown the device maintains an error margin below 5%, proving it to be both user-friendly and medically reliable.

Beyond Smartwatches and Conventional Portable ECGs

Unlike smartwatches—which typically offer only 1-lead ECG readings and simple heart rate data—heartGO is equipped with 6-leads, approaching the clinical standard of hospital ECGs (12-leads).

This device is capable of simultaneously measuring four key heart function parameters: heart rate, QT interval duration, QRS complex duration, and heart rate variability. With these capabilities, heartGO can generate ECG signals in graphical form that closely resemble those produced by professional-grade equipment, making it suitable for preliminary medical consultations. Most other portable ECG devices remain limited to chest-based measurements and have yet to offer results as comprehensive as heartGO.

Integrated Mobile App: Record, Store, and Analyze Heart History

HeartGO comes with an integrated mobile app that simplifies heart health monitoring. On the Home screen, users can instantly view ECG data and detect early signs of abnormality. The Record feature allows users to capture ECG signals for customizable durations, from 30 seconds to 5 minutes—making it adaptable for various scenarios.

Each recording is automatically saved in the History section, helping users track and analyze heart data over time. Comprehensive results can be exported as a PDF file complete with graphs and parameter summaries, making heartGO a practical and valuable tool for personal health management and medical consultations.

Designed from Real-World Challenges, Developed with Precision

Alika and heartGO team was motivated by the limited public access to ECG tests, which are typically only available in secondary and tertiary healthcare facilities and require professional operators. Traditional ECG machines are also large and not easily accessible.

“Since most medical ECG devices are bulky and require trained professionals, we saw that many people struggle to access heart check-ups. That’s what inspired us to create something smaller, portable, and usable by anyone, anywhere,” said Azka.

Although the team faced challenges such as sourcing electronic chips and implementing data plotting within the app, they successfully completed the development within a semester. They utilized stainless steel electrodes for efficient signal transmission from the body to the sensor, and an ADS1293 chip to convert analog signals into digital data before sending it to the app.

Toward a More Inclusive Future in Healthcare

With its user-friendly design, clinical-grade functionality, and portability, heartGO is a promising step toward more inclusive and independent heart health monitoring. More than just a technological innovation, heartGO offers a real-world solution for people seeking a convenient, affordable, and accessible way to take care of their heart—wherever they are.
