Abstract Electronic textiles have gradually evolved into one of the most important mainstays flexible electronics owing to their good wearability. However, textile multifunctionality is generally achieved by stacking functional modules, which not conducive Integrating these modules a single fiber provides better solution. In this work, core‐spun (CSF) constructed from hyper‐environmentally stable Zn‐based eutectogel as core layer and polytetrafluoroethylene sheath designed. The CSF achieves synergistic output effect piezoelectricity‐enhanced triboelectricity, well reliable hydrophobicity, high mid‐infrared emissivity visible light reflectivity. A monolayer functionalized integrated woven enable effective energy (mechanical droplet energy) harvesting personal thermal management functions. Furthermore, scenarios for supply, motion detection, outdoor use electronic fabrics applications are demonstrated, opening new avenues integration textiles.

Abstract Although dielectric elastomer actuators (DEAs) are promising artificial muscles for use as visual prostheses in patients with oculomotor nerve palsy (ONP), high driving voltage coupled vulnerable compliant electrodes limits their safe long‐term service. Herein, a self‐healable polydimethylsiloxane electrode based on reversible imine bonds and hydrogen is prepared coated an acrylic ester film to develop DEA (SDEA), followed by actuation high‐output triboelectric nanogenerator (TENG) construct self‐powered (TENG‐SDEA). Under 135.9 kV mm −1 , the SDEA exhibits elevated actuated strain of 50.6%, comparable under DC power. Moreover, mechanically damaged TENG‐SDEA displays self‐healing efficiency over 90% 10 cycles. The TENG ensures using TENG‐SDEAs extraocular‐muscle‐like actuator oriented motion ability integrated several constructed. Additionally, directly used flexible capacitive sensor real‐time monitoring patient's muscle movement. Accordingly, medical aid system conjunction manufactured help suffering from ONP physical rehabilitation treatment.
