Abstract Flexible ionic conductors hold potential for wearable sensors and energy harvesting. However, most gel‐based suffer from solvent evaporation liquid leakage, limiting practical applications. Although solid‐state mitigate these issues, achieving strong mechanics, high conductivity, self‐healing, stability remains challenging. Here, by integrating supramolecular engineering dynamic covalent adaptive networks, a self‐healing polyurethane‐based ion‐conductive elastomer (DACPU/100Li) with outstanding overall properties is successfully synthesized. DACPU/100Li exhibits ultrahigh conductivity (1.23 × 10 − 3 S cm −1 ) tensile strength (7.62 MPa), along an elongation at break of 1200%. Additionally, it excellent tear resistance fracture 45.6 kJ m 2 , 96% efficiency (after 120 °C 24 h), good recyclability, under extreme conditions. The DACPU/100Li‐based sensor has sensitivity (5.89) wide strain range (0.1–1000%). Integrated machine learning, enables precise gesture recognition human–machine interaction. Furthermore, the triboelectric nanogenerator based on achieves power density 3.87 W . It harvests body motion to small devices aids object via learning. believed that elastomers provide new opportunities electronics, harvesting, ionotronics.

Abstract Eutectogels, a family of emerging materials, integrate the characteristics deep eutectic solvents (DES) and gels, presenting unique application potential in biomedical engineering. However, latest progress eutectogels their applications field remain to be summarized refined. This review first introduces composition properties generated by interaction between DES gel matrix. Subsequently, classifications advantages are comprehensively discussed according cross‐linked preparation methods, including physical, chemical, multiple cross‐linked. By analyzing eutectogels, such as mechanical performance, thermal properties, conductivity, injectability, structure‐function relationships, is overviewed. Then, eutectogel's prospects engineering elaborated detail, drug delivery improve stability precise control release, enhancing curative effects reducing side effects. Also, functional utilization tissue engineering, biosensing, bioadhesives, related domains explored. Finally, existing challenges prospective research directions delineated.
