Abstract The rapid advancement in attractive platforms such as biomedicine and human‐machine interaction has generated urgent demands for intelligent materials with high strength, flexibility, self‐healing capabilities. However, existing ability are challenged by a trade‐off between low elastic modulus, healing due to the inherent strength of noncovalent bonding. Here, drawing inspiration from human fibroblasts, monomer trapping synthesis strategy is presented based on dissociation reconfiguration amphiphilic ionic restrictors (7000‐times volume trapping) develop eutectogel. Benefiting nanoconfinement dynamic interfacial interactions, molecular chain backbone formed confined domains mechanically reinforced while preserving soft movement resulting eutectogels demonstrate superior mechanical properties (1799% 2753% higher tensile toughness than pure polymerized deep eutectic solvent), excellent efficiency (>90%), tangential modulus (0.367 MPa during working stage), sensitively monitor activities. This poised offer new perspective developing wearable electronics tailored body motion.

Abstract Flexible temperature sensors often use gels to achieve skin‐inspired softness, but the water evaporation and freezing of hydrogel leakage ionogel, cause unstable signal transmission inaccurate measurement at sub‐zero temperatures. Here steady hypothermic sensing is achieved by designing a supramolecular elastomer containing two types segments: liquid‐free iontronic segment transmit electrical charges prevent ion leakage, neutral with pendant chains damp vibration for stable transmission. The exhibits excellent tensile properties, adhesiveness, self‐healing, ionic conductivity A wireless system fabricated based on supermolecule elastomer, realizing accurate, steady, sensitive real‐time detection. Especially, sensor coefficient resistance (TCR) 8.87% °C −1 from −20 −15 °C, three five times higher than that most flexible sensors. There no significant difference in detected this an infrared thermal imaging camera. Such represents step toward highly accurate cold chain transportation beyond.

Abstract Liquid metal nanoparticles (LMNPs) are being considered as promising candidates for printable electronics owing to their high conductivity and fluidity, well improved wettability comparable that of bulk LMs. However, the surface tension weak adhesion LMNPs pose formidable challenges facile patterning on various substrates diverse applications. Herein, a new LMNP‐polymer composite is reported multifunctional electronics, which achieved by introducing α ‐lipoic acid (LA)/choline chloride (ChCl) polymerizable deep eutectic solvents (PDESs) ideal polymer carriers. Simply with ring‐opening polymerization (ROP) LA, highly conductive LMNP‐PDES composites can be patterned using printing methods. Benefiting from hydrogen bondings within PDES, printed traces feature enhance consistent performances under different deformations. More importantly, they easily dissolved in ethanol via thermal treatment reprinted further use, showing excellent recyclable capability. Demonstrations stretchable sensor, conformal electrode, smart actuator validate versatility reliability this composite, ensuring its broad prospects electronics.

Abstract Conductive hydrogels (CHs) are attracted more attention in the flexible wearable sensors field, however, how to stably apply CHs underwater is still a big challenge. In order achieve usage of aquatic environments, integrated properties such as water retention ability, resistance swelling, toughness, adhesiveness, linear GF sensing, and long‐term necessary consider, but rarely reported previous reports. This paper proposes prepared using cationic aromatic monomers along with polyrotaxanes‐based crosslinkers. Due intermolecular cation‐π interactions topological slide‐ring‐based polyrotaxanes, exhibit good mechanical performance, adhesive nature, anti‐swelling properties. The presence architecture effectively mitigates stress concentration. Additionally, encapsulation PA allows maintain functionality even after 240 days direct placement at room temperature. Notably, designed sensitivity detecting land/underwater human motions, serve Morse code signal transmitters for information transmission. Thus, may have broad applications field.

Abstract Ionogels filled with non‐volatile ionic liquids effectively mitigate issues such as solvent volatilization, making them suitable for flexible sensors. However, it remains challenging to fabricate recyclable ionogels outstanding mechanical properties, high transparency, and capabilities. In this study, a transparent ionogel dynamic networks is prepared by in situ polymerization of thioctic acid (TA) polyvinyl pyrrolidone (PVP) halometallate liquid. Due the abundant crosslinks formed between liquid PTA along rigidity PVP, exhibited excellent strength (≈6.14 MPa), satisfying stretchability (≈1000%), toughness (≈20.08 MJ m −3 ). Meanwhile, displayed UV shielding capability, recyclability, reprocessability. Enabled electrochemical can be used sensors, demonstrating good sensitivity stability repeatable use. This work provides straightforward approach synthesizing high‐performance sensing applications.

Metal adhesive synthesis typically involves heating and solvents, the resultant adhesives lack degradability suffer from recycling sustainable problems. Herein, we developed a solvent-free chemically degradable biobased (p(Elp-TA)+PVP) thioctic acid (TA), its derivative (Elp), polyvinylpyrrolidone (PVP). Through rapid acid-triggered cationic ring-opening polymerization of dithiolane at ambient conditions, p(Elp-TA)+PVP could build up strong lap shear strength 1123 kPa in air an underwater 534 to copper plate. Molecular dynamics simulations show that compared p(Elp-TA), presence appropriate amount PVP can significantly enhance binding energy molecules metal substrate, adhesion substrates was achieved through synergistically dynamic adaptive network enhanced by hydrogen bonding, reversible coordination bonding 40 ps. More importantly, applied be easily degraded reverted small-molecular-weight lipoic species.
