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.

Wearable cardiovascular monitoring systems demand electrodes that are simultaneously highly conductive, mechanically compliant, and biocompatible , while maintaining stable signal quality during continuous use. Conventional rigid or weakly stretchable electrodes often suffer from poor skin conformity, motion artifacts, and signal degradation—limiting their reliability in real‑world monitoring. This review addresses these challenges through the development of ultra‑stretchable
