    "body_text": "Researchers developed PPGA-Al, a soft hydrogel interface designed to sit between wearable electrodes and moving skin. The material combines a flexible polymer network, gelatin, silver nanowires, ions, and reversible molecular bonds so it can remain adhesive and conductive without becoming rigid or drying quickly. Tests captured ECG, EMG, and EEG signals under conditions including motion, perspiration, and oily skin. The work addresses a persistent interface problem in long-term monitoring, but the reported material is a research platform rather than a cleared medical wearable.",
