Abstract Practical applications of existing self‐healing ionogels are often hindered by the trade‐off between their mechanical robustness, ionic conductivity, and temperature requirements for ability. Herein, this challenge is addressed drawing inspiration from sea cucumber. A polyurethane containing multiple hydrogen‐bond donors acceptors synthesized used to fabricate room‐temperature with excellent properties, high puncture resistance, impact resistance. The hard segments polyurethane, driven hydrogen bonds, coalesce into phase regions, which can efficiently dissipate energy through reversible disruption reformation bonds. Consequently, resulting exhibit record‐high tensile strength toughness compared other ionogels. Furthermore, inherent reversibility bonds within regions allows spontaneously self‐heal damaged properties conductivity times at room temperature. To underscore application potential, these employed as electrolytes in fabrication electrochromic devices, stable performance, repeatable healing ability, satisfactory This study presents a novel strategy exceptional capability.

Abstract Polymer gels are versatile materials in biomedical applications, sensors, and actuators. However, designing with diverse functionalities, such as high toughness, self‐healing capability, 3D printability, is often challenging. In this work, it found that random copolymerization of N ‐isopropyl acrylamide (NIPAm) a small amount acrylic acid (AAc) hydrophobic eutectic solvent consisting menthol decanoic leads to eutectogels toughened by polymer‐solvent hydrogen bonding. Interestingly, further increasing AAc content induced phase separation glassy AAc‐riched domain significantly increased the stiffness eutectogels. The stretchability poly(NIPAm‐co‐AAc) can also be easily modulated adjusting monomer concentration, leading highly transparent toughness. Furthermore, demonstrate efficient dissipation, reasonable recovery, moderate capability. resin compatible digital light processing printing prepare dielectric layers different geometric designs for capacitive sensors. By integrating functions printing, approach provides new avenue soft broad palette mechanical properties geometrical designs.

Physical eutectogels as a newly emerging type of conductive gel have gained extensive interest for the next generation multifunctional electronic devices. Nevertheless, some obstacles, including weak mechanical performance, low self-adhesive strength, lack self-healing capacity, and conductivity, hinder their practical use in wearable strain sensors. Herein, lignin green filler hydrogen bond donor was directly dissolved deep eutectic solvent (DES) composed acrylic acid (AA) choline chloride, lignin-reinforced physical (DESL) were obtained by polymerization AA. Due to unique features DES, prepared DESL exhibit good transparency, UV shielding excellent outstanding self-adhesiveness, superior properties, high conductivity. Based on aforementioned integrated functions, sensor displaying wide working range (0-1500%), sensitivity (GF = 18.15), rapid responsiveness, stability durability (1000 cycles) capable detecting diverse human motions fabricated. Additionally, combining sensors with learning technique, gesture recognition system accuracy 98.8% achieved. Overall, this work provides an innovative idea constructing multifunction-integrated application electronics.
