Addressing Signal Stability in Wearable Bioelectronics Reliable wearable electrocardiography (ECG) and blood pressure monitoring require electrode materials that are soft, conductive, mechanically stable, and biocompatible , while maintaining strong and durable skin–electrode interfaces. In practice, many existing wearable electrodes suffer from interfacial degradation, signal drift, and motion‑induced noise , limiting their effectiveness for long‑term, real‑world monitoring.
