ABSTRACT Eutectic gels have great advantages in the application of flexible wearable electronic devices due to their good stability and flexibility. However, adhesion properties current eutectic are poor processing process is complicated. Based on this, this study proposed a gel with excellent that can be photocurable for 3D printing. We designed polymerizable deep solvent (PDES) using acrylic acid as main monomer, acid/choline chloride (AA/ChCl) solvent, dopamine‐grafted cellulose nanocrystals (DC) nanoscale crosslinking agent. The introduction DC endows denser hydrogen bond network, which effectively provide energy dissipation improve mechanical gel. mussel‐inspired dopamine into network gives adhesion. low freezing point volatility PDES give resistance long‐term storage stability. Furthermore, has sensitivity factor up 9.5 (at 0%–900% strain), showing strain sensing performance. In addition, not only realize customization various complex structures through digital light (DLP) printing technology, but also manufactured complete accurate signals human body. Therefore, combination multi‐performance compatible materials technology will new idea design manufacture devices.

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.
