Nevertheless, developing a stretchable hydrogel actuator combining remote actuation and real-time signal feedback remains a challenge. Herein, a light-responsive hydrogel actuator with self-sensing function is fabricated by employing a localized immersion strategy to incorporate polyacrylamide (PAM) hydrogel network into semi-interpenetrating carbon nanotube/2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofiber/poly(N-isopropylacrylamide) (CNT/TOCN/PNIPAM) hydrogel. CNTs impart photothermal response and electrical conductivity to the hydrogels. TOCNs facilitate the dispersion of CNTs and improve the mechanical properties of the hydrogel. The introduction of PAM further reinforces the mechanical strength and promotes the formation of gradient structure, which can prevent interlayer separation during the actuating process. The optimized CNT/TOCN/PNIPAM-PAM hydrogel actuator with enhanced tensile strength (53.0 kPa), stretchability (131.1 %), conductivity (2.5 S m<sup>−1</sup>) and reversible near-infrared (NIR) light responsiveness (bending velocity 6.25° s<sup>−1</sup>) enables a variety of precise and remote light-responsive deformations. The conductive hydrogel-based strain sensor with high sensitivity (gauge factor, 3.6) can rapidly and accurately identify various human movements. Notably, the hydrogel can perceive its actions driven by NIR light through real-time resistance changes, realizing closed-loop monitoring and sensing feedback, which provided new insights for novel soft biomimetic actuating materials and integrated multi-functional devices.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"368 ","pages":"Article 124092"},"PeriodicalIF":10.7,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144670464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a marine organism-inspired tough and adhesive patch (MOTAP) was developed to address these challenges. Inspired by the tough shell of crustacean chitin, the thermosensitive quaternized derivative was employed to engineer a film with exceptional mechanical strength.

This patch exhibits great mechanical property, excellent adhesive strength (175 kPa), and an ultrahigh burst pressure (92 kPa). MOTAP robustly seals various tissues, effectively prevents the leakage of corrosive gastrointestinal fluids, and rapidly induces coagulation. Compared to commercial and clinical materials, MOTAP demonstrates superior efficacy in sealing perforated stomachs, achieving hemostasis, and promoting wound healing.

The pathogenesis of diabetic microvascular complications is highly complex, involving multidimensional interactions encompassing metabolic disorders, oxidative stress, and inflammatory cascades.
