A novel flexible wireless ECG module demonstrates technical feasibility and electromagnetic compatibility for continuous heart rate variability monitoring.
Supports wearable ECG development; leaves open clinical validation for continuous monitoring.
The rigidity of printed circuit boards (PCB) constrains the assembly and utility of most existing electrocardiogram (ECG) circuits. Moreover, the literature seldom discusses electromagnetic compatibility (EMC) in the context of ECGs. This paper presents a wireless ECG module built on a flexible printed circuit board (FPCB) and EMC measurement. A flexible wireless module for ECG signals monitoring was designed with high input impedance, a high common-mode rejection ratio (CMRR), low-power consumption, and appropriate amplification and filtration, which automatically cancels offset voltage. The device detects some bioparameters such as heart rate variability (HRV). In addition, EMC test results show the device does not affect normal ECG operation. In the proposed approach, the module accommodates the acquisition of other biomedical signals if the module's gain and pass-band are modified.
