Open-source low-cost non-contact ECG monitoring system using active dry electrodes.

ABSTRACT: Continuous electrocardiogram (ECG) monitoring is essential for the early detection of cardiac arrhythmias and other heart conditions. However, conventional wet electrode-based systems often cause skin irritation and signal degradation, making them uncomfortable and unsuitable for long-term daily use. In this study, we present a fully open-source, low-cost (∼$14), miniaturized (∼50 × 35 × 28 mm³), and lightweight (∼60 g), wearable ECG monitoring platform that uses non-contact, active, dry electrodes based on capacitive coupling. The system integrates ultra-high input impedance electrode circuitry, an analog front-end integrated circuit, Bluetooth wireless communication, and an Android mobile application for real-time signal visualization and storage.
