A Skin-Like Hydrogel Keeps Wearable ECG, EMG and EEG Sensors Working Through Sweat and Motion

Researchers created a soft adhesive hydrogel that bridges rigid wearable electrodes and moving human skin while resisting drying and signal loss. The material produced stable ECG, EMG and six-hour EEG recordings under demanding conditions, but its evidence remains limited to controlled prototype testing rather than long-term clinical use.
