The compact design of an environmentally adaptive battery and effectors forms the foundation for wearable electronics capable time-resolved, long-term signal monitoring. Herein, we present a one-body strategy that utilizes hydrogel as ionic conductive medium both flexible aqueous zinc-ion batteries strain sensors. poly(vinyl alcohol) network incorporates nano-SiO2 cellulose nanofibers (referred to PSC) in ethylene glycol/water mixed solvent, balancing mechanical properties (tensile strength 6 MPa) diffusivity at −20 °C (2 orders magnitude higher than 2 M ZnCl2 electrolyte). Meanwhile, cathode lattice breathing during solvated Zn2+ intercalation dendritic Zn protrusion anode interface are mitigated. Besides robust cyclability Zn∥PSC∥V2O5 prototype within wide temperature range (from 80 °C), this microdevice seamlessly integrates with sensor, enabling precise monitoring muscle response dynamic body movement. By employing transmission-mode operando XRD, self-powered sensor accurately documents real-time phasic evolution layered synchronized change induced by deposition, which presents feasible solution health miniaturized electronics.

Abstract Conductive hydrogels are gaining significant attention as promising candidates for the fabrication materials flexible electronics. Nevertheless, improving tensile properties, hysteresis, durability, adhesion, and electrochemical properties of these remains challenging. This work reports development a novel semi‐interpenetrating network poly(ionic liquid) hydrogel named PATV, via in situ polymerization acrylamide, N ‐[Tris(hydroxymethyl)methyl] 1‐vinyl‐3‐butylimidazolium tetrafluoroborate. The density functional theory calculations reveal that acts physical cross–linking points to construct hydrogen‐bond networks. Furthermore, networks dissipate energy efficiently quickly, thus stress concentration hysteresis avoided. prepared has low (9%), high (900%), fast response (180 ms), sensitivity (gauge factor = 10.4, pressure 0.14 kPa −1 ), wide sensing range (tensile range: 1–600%, compression 0.1–20 kPa). A multifunctional sensor designed based on enables real‐time, rapid, stable response‐ability detection human movement, facial expression recognition, pronunciation, pulse, handwriting, Morse code encryption. assembled triboelectric nanogenerator displays an excellent harvesting capability, highlighting its potential application self‐powered wearable electronic devices.

Conductive hydrogels exhibit high potential in the fields of wearable sensors, healthcare monitoring, and e-skins. However, it remains a huge challenge to integrate elasticity, low hysteresis, excellent stretch-ability physical crosslinking hydrogels. This study reports synthesis polyacrylamide (PAM)-3-(trimethoxysilyl) propyl methacrylate-grafted super arborized silica nanoparticle (TSASN)-lithium chloride (LiCl) hydrogel sensors with electrical conductivity. The introduction TSASN enhances mechanical strength reversible resilience PAM-TSASN-LiCl by chain entanglement interfacial chemical bonding, provides stress-transfer centers for external-force diffusion. These show outstanding (a tensile stress 80-120 kPa, elongation at break 900-1400%, dissipated energy 0.8-9.6 kJ m
