Advanced Science, Год журнала: 2024, Номер 11(39)

Опубликована: Авг. 20, 2024

Abstract Hydrogel sensors are widely utilized in soft robotics and tissue engineering due to their excellent mechanical properties biocompatibility. However, high‐water environments, traditional hydrogels can experience significant swelling, leading decreased electrical performance, potentially losing shape, sensing capabilities. This study addresses these challenges by leveraging the Hofmeister effect, coupled with directional freezing salting‐out techniques, develop a layered, high‐strength, tough, antiswelling PVA/MXene hydrogel. In particular, process enhances self‐entanglement of PVA, resulting an S‐PM hydrogel tensile strength up 2.87 MPa. Furthermore, retains its structure after 7 d only 6% change resistance. Importantly, performance is improved postswelling, capability rarely achievable hydrogels. Moreover, demonstrates faster response times more stable resistance rates underwater tests, making it crucial for long‐term continuous monitoring challenging aquatic ensuring sustained operation monitoring.

Опубликована: Ноя. 6, 2024

Abstract Intelligent wearable sensors based on MXenes hydrogels are rapidly advancing the frontier of personalized healthcare management. MXenes, a new class transition metal carbon/nitride synthesized only decade ago, have proved to be promising candidate for soft sensors, advanced human–machine interfaces, and biomimicking systems due their controllable high electrical conductivity, as well unique mechanical properties derived from atomistically thin layered structure. In addition, MXenes’ biocompatibility, hydrophilicity, antifouling render them particularly suitable synergize with into composite mechanoelectrical functions. Nonetheless, while use MXene multifunctional surface or an current collector such energy device electrode is prevalent, its incorporation gel system purpose sensing vastly less understood formalized. This review provides systematic exposition synthesis, property, application intelligent sensors. Specific challenges opportunities synthesis adoption in practical applications explicitly analyzed discussed facilitate cross gemination across disciplines advance potential hydrogels.
