Solar Powered ECG Monitoring System

This paper presents the design and implementation of a solar-powered electrocardiogram (ECG) monitoring system for continuous cardiac health surveillance in remote and resource-limited environments. The system integrates a high-precision ECG acquisition module with solar energy harvesting technology to enable autonomous operation without dependence on conventional power infrastructure. The device incorporates low-power analog front-end circuitry for signal conditioning, a microcontroller-based processing unit for real-time ECG analysis, and wireless communication capabilities for remote data transmission. The solar power subsystem utilizes photovoltaic panels coupled with efficient maximum power point tracking (MPPT) algorithms and rechargeable battery storage to ensure continuous operation during varying lighting conditions. The ECG monitoring module employs advanced filtering techniques to minimize noise and artifacts while maintaining clinical-grade signal quality. Real-time heart rate variability analysis and arrhythmia detection algorithms are implemented to provide immediate health status alerts.
