Inspiration
The inspiration behind the Smart Elder Health Tracker came from the growing need for proactive elder care. As populations age, it becomes crucial to monitor the health of elderly family members in real-time, especially for those living alone. Many families worry about potential health risks like falls, abnormal heart rates, or irregular breathing patterns. With advancements in wearable technology, we wanted to develop a solution that not only tracks health parameters but also provides peace of mind by sending real-time updates to family members or caregivers.
What it does
The Smart Elder Health Tracker is a wearable device designed to monitor vital health metrics and activity levels in real-time. Its key features include: Heart Rate Monitoring: Tracks heart rate, detecting irregularities. Blood Oxygen (SpO2) Monitoring: Measures oxygen levels in the blood to ensure proper respiration. Fall Detection: Uses motion sensors to detect falls and immediately sends an SOS alert to family members. Sleep Tracking: Monitors sleep quality and cycles, providing insights into restfulness. Temperature Sensor: Tracks body temperature to detect early signs of illness. Real-Time Data Sharing: Transmits health data to a companion app, allowing family members to monitor the user remotely. Emergency SOS Button: Provides a panic button for quick assistance during emergencies, sending location and health data instantly. Medicine Reminders: The device sends notifications or reminders to the user about when to take their medicine.
How we built it
Wearable Device: We integrated multiple sensors such as a heart rate monitor, SpO2 sensor, accelerometer, gyroscope, and temperature sensor into a compact wearable form factor. Communication Protocol: We used Bluetooth Low Energy (BLE) to connect the wearable to a companion mobile app, ensuring energy-efficient data transmission. Mobile App: The app was developed using Flutter for cross-platform functionality. It syncs with the wearable to store and visualize data, while also allowing caregivers to receive real-time updates.
Challenges we ran into
Sensor Integration: Ensuring that all the sensors work seamlessly together without draining too much battery was a major challenge. Fall Detection Accuracy: Differentiating between a fall and normal movements, like sitting down abruptly, posed difficulties in developing a reliable algorithm. Battery Life Optimization: Keeping the device small while ensuring a long battery life was a challenge due to the number of sensors and real-time data transmission.
Accomplishments that we're proud of
Accurate Real-Time Health Monitoring: Successfully integrating multiple health sensors into a compact device with accurate real-time tracking of vital signs. Reliable Fall Detection: Developing an algorithm that accurately detects falls and reduces false positives. User-Friendly App: Building an intuitive app interface that allows family members to easily monitor their loved one’s health and receive timely alerts.
What we learned
Importance of User Experience: Through testing, we learned that for elderly users, simplicity is key. We improved the UI/UX of the app to ensure ease of use and focused on making the wearable comfortable and lightweight. Sensor Calibration: We gained experience in calibrating sensors for accurate data collection and learned how to manage power consumption effectively. Data Security: Managing sensitive health data taught us the importance of stringent data protection measures, including encryption and secure cloud storage.
What's next for Smart Health Tracker
Advanced AI Insights: We plan to integrate AI algorithms to detect early warning signs of health issues based on patterns in the data, such as early indicators of heart disease or respiratory issues. More Sensors: Adding non-invasive blood glucose monitoring and hydration tracking would make the device more comprehensive. Telemedicine Integration: We aim to integrate telemedicine features, allowing users to share their health data with doctors directly through the app for remote consultations.
