Key Points
- Design and evaluate a wearable, noncontact wireless ECG monitoring system using flexible dry capacitive electrodes to record cardiac signals through clothing for long-term health tracking.
- Fabricated flexible, dry capacitive-coupled electrodes designed to detect cardiac electrophysiological signals across textile interface layers.
- Integrated a low-power data acquisition unit that transmits raw ECG signals via Bluetooth to a custom computer application for real-time filtering, storage, and display.
- Tested signal fidelity across multiple textile fabrics and during physical body movements, alongside a comparative analysis of modern ambulatory and commercial ECG platforms.
- Maintained clear, real-time ECG signal acquisition through various textile materials without requiring direct conductive skin contact.
- Preserved adequate signal integrity during active body motion, demonstrating performance consistent with existing ambulatory ECG benchmark systems.
