ABSTRACT Conductive hydrogels with ionic compounds possess great potential for the development of soft smart devices. A dielectric scarfskin is typically required these devices to prevent short circuiting, leading lower stretchability than hydrogel. Henceforth, commonly used materials, such as PDMS and Ecoflex, cannot be largely stretched. Hydrogel ultrastretchability are accommodate hostile application environments. Herein, we propose a hydrogel fiber coated layer that can stretched over 2000% its initial length. The remains conductive when ~1300%. In addition, core/sheath endowed variety functional properties, electroluminescence (EL), photoluminescence (PL), magnetic‐responsiveness, demonstrating scalability resultant fiber. present work pave way numerous next‐generation devices, textiles wearable electronics. © 2019 Wiley Periodicals, Inc.
