Fibrous material with high strength and large stretchability is an essential component of high-performance wearable electronic devices. Wearable systems require a that strong to ensure durability stability, wide range strain expand their applications. However, it still challenging manufacture fibrous materials simultaneously mechanical the tensile property. Herein, ultra-robust (≈17.6 MPa) extensible (≈700%) conducting microfibers are developed demonstrated applications in fabricating...

Abstract Conductive hydrogels have been promising candidates for wearable and flexible electronics due to their high flexibility biocompatibility. However, the previously reported with conductivity over 1000 S m −1 usually poor mechanical properties including low tensile stress (<5 MPa) toughness (<2 MJ −3 ). Here, a liquid metal‐doped polyvinyl alcohol (PVA‐LM) hydrogel is presented, which simultaneously combines ultra‐high (maximum of 217 895 ) excellent properties, (15.44 MPa),...

Materials with programmable conductivity and stiffness offer new design opportunities for next-generation engineered systems in soft robotics electronic devices. However, existing approaches fail to harness variable electrical mechanical properties synergistically lack the ability self-respond environmental changes. We report an electro-mechano responsive Field's metal hybrid elastomer exhibiting tunable conductivity, strain sensitivity, stiffness. By harnessing these properties, we...

Conductive elastic composites composed of conductive fillers and polymer matrices are showing an increasing number applications in the fields flexible sensors, wearable devices, stretchable electronics. Under mechanical deformation, filler network matrix shifts to change pathway among particles thus, electrical conductivity composite. For most composites, their changes monotonically with strain. Here, we report a composite that exhibits unconventional strain response; its increases sharply...

In recent years, the demand for wearable strain sensors is growing due to their motion monitoring and clinical data collection capabilities. The with positive piozeconductivity, i.e. conductivity increases when stretched, are more favored in electronics because they can maintain high under stretching. However, reported composites piezoconductivity mostly show low sensitivity. Furthermore, few electronic systems based on built completely processing Herein, we present a sensor piezoconductive...
