Hydrogel-based sensors typically demonstrate conspicuous swelling behavior in aqueous environments, which can severely compromise the mechanical integrity and distort sensing signals, thereby considerably constraining their widespread applicability. Drawing inspiration from multilevel heterogeneous structures biological tissues, an antiswelling hydrogel sensor endowed with high strength, rapid self-recovery, low ratio was fabricated through a water-induced phase separation coordination cross-linking strategy. A dense architecture developed by integration of "rigid" quadridentate carboxyl-Zr4+ bonds "soft" hydrophobic unit-rich regions featuring π-π stacking cation-π interactions into hydrogels. This unique structural design facilitated progressive breaking cross-links within network to under external loads, effectively dissipating energy imparting hydrogels exceptional characteristics, evidenced strength 1.42 MPa, complete self-recovery 3 min. Simultaneously, dynamic synergistically conferred augmented elastic retractive forces on enhancing density, providing prominent capabilities water (with only -2.49%), solutions diverse pH (1-9), seawater. Moreover, manifested favorable strain-sensitivity (gauge factor up 2.45) frequency response virtue collaborative contribution ions (Cl- Zr4+). Consequently, were utilized assemble underwater capacity transmit information using Morse code. bioinspired methodology achieved desired mechanical, swelling-resistant, performance hydrogels, contributing innovative insights toward advancement technology.

Abstract The fabrication of molecular cluster‐based intelligent energy storage systems remains a significant challenge due to the intricacies multifunctional integration at level. In this work, low‐valent metal atoms are successfully encapsulated within ɛ ‐type Keggin structures, yielding novel cluster denoted as CuMo 16 . This unique structure displayed characteristic “molybdenum red” coloration, with high degree reduction (76.47%), which played pivotal role in enhancing its electrochemical properties. specialized configuration significantly enhanced multi‐proton‐coupled electron transfer kinetics, enabling efficient and rapid release, up thirteen electrons per molecule. To construct an device, is employed proton‐coupled electron‐active material embedded polyvinyl alcohol (PVA) matrix, resulting flexible, wearable, rechargeable devices. flexible electronics not only demonstrate real‐time human motion detection but also exhibit remarkable performance, reaching peak capacity 194.19 mAh g −1 maintaining 68.2% retention after 2500 cycles. Molecular dynamics simulations reveal that integrating enhances performance electronics, regulation content provides effective strategy for optimizing electronic study lays foundation development systems.
