Abstract
Stretchable conductive hydrogels have emerged as ideal interfaces for seamless and biocompatible integration with human skin, showing significant potential in medical electronic applications. However, achieving a balance between high mechanical robustness and excellent electrical conductivity remains challenging, particularly for electromyography (EMG) and electrocardiography (ECG) sensing. Here, a high-performance conductive hydrogel sensor is fabricated by incorporating a mechanically interlocked polyrotaxane into a topological network. The resulting hydrogel exhibits a remarkable combination of properties: ultrahigh stretchability (2488%), high electrical conductivity (5.1 S/m), tissue-like strength (65…
