Design and development of a wearable device for real-time health monitoring and telemedicine

Wearable medical devices have evolved from basic fitness trackers to sophisticated health-monitoring tools capable of acquiring vital physiological parameters. This paper presents the design and development of an enhanced version of the PulsECG, a wearable device aimed at real-time health monitoring. The upgraded smartwatch integrates electrocardiogram (ECG), photoplethysmography (PPG) for oxygen saturation measurement, a body temperature sensor, and an accelerometer for movement analysis. The system features optimized printed circuit board (PCB) design, low-power consumption, and data transmission via Bluetooth to a smartphone application. The added temperature and motion sensors enhance the device’s ability to monitor user activity and detect potential health anomalies, making it particularly useful for telemedicine applications and chronic disease management. Compared to traditional medical monitoring systems, this wearable device offers a non-invasive and convenient solution for continuous health tracking. Validation tests demonstrate the device’s ability to acquire reliable ECG, PPG, motion, and temperature data, while maintaining user comfort and ease of use, supporting its application in telemedicine and continuous health tracking. The presented advancements contribute to the growing field of wearable healthcare technology, improving accessibility and efficiency in remote patient monitoring.
