Laser-Engraved Porous Breathable Hydrogels for Wearable Electrocardiogram Monitoring.

Accurate diagnosis of cardiovascular diseases relies on reliable electrocardiogram (ECG) monitoring. However, conventional hydrogel electrodes exhibit poor air permeability, and prolonged application tends to result in problems including degraded signal quality and skin discomfort. In this study, a polyelectrolyte doub...
