Thickness‐Gradient Liquid Metal Connectors for Seamless Electrophysiological Sensors

Advanced Science, EarlyView.
Thickness‐gradient liquid metal interfaces with elastomeric substrates enable seamless integration between ultrathin skin‐conformal electrodes and external interconnects. The mechanically compliant connector reduces interfacial mismatch and supports stable ECG/EMG monitoring under bending and motion.
