This paper introduces an innovative 12-lead Electrocardiogram (ECG) monitoring system engineered for optimal user comfort, showcasing its prototype iterations. The system incorporates novel dry electrodes integrated seamlessly into wearable garments such as shirts and shorts. These electrodes facilitate dynamic adjustment of the precordial leads through a hook-and-loop fastening mechanism, commonly known as Velcro, enhancing the adaptability of electrode placement. The system’s precordial leads, encompassing V1 to V9 and V3R to V6R, are adept at capturing standard ECG readings during various sleep phases. For ambulatory monitoring, particularly during walking, the system employs a unique split sleeve approach on limb leads, characterized by an elastic band at the cuffs that doubles as a conductive electrode. Additionally, the Velcro mechanism on these bands enables fine-tuning of the conductive properties, thus acting as a filter to enhance the fidelity of ECG signal acquisition in motion. This advanced system holds potential for application in both 12-lead Holter monitoring and dedicated sleep ECG monitoring scenarios.
