Abstract The fast progress in electronic devices demands superior anti‐reflective performance of electromagnetic interference shielding materials. However, high‐performance strategies are mainly dependent on reflection effects and this inevitably results a trade‐off between properties during structural designs. Herein, work proposes novel gradual heterogeneity design to fundamentally overcome the contradiction. different steric hindrances MXene nanosheets aramid nanoclusters endow competitively assembled laminal aerogel films with unique Janus architecture.

Abstract As skin bioelectronics advances, hydrogel wearable devices have broadened perspectives in environment sensing and health monitoring. However, their application is severely hampered by poor mechanical self‐healing properties, environmental sensitivity, limited sensory functions. Herein, inspired the hierarchical structure unique cross‐linking mechanism of hagfish slime, a self‐powered supramolecular hereby reported, featuring high stretchability (>2800% strain), ultrafast autonomous capabilities (electrical healing time: 0.3 s), self‐adhesiveness (adhesion strength: 6.92 kPa), injectability, ease shaping, antimicrobial biocompatibility. It observed that embedding with highly hygroscopic salt LiCl hydrogel, not only showed excellent electrical conductivity but also presented favorable anti‐freezing water retention properties extremely cold environments natural settings. Given these attributes, served as multifunctional durable device sensitivity (gauge factor: 3.68), fast response time (160 ms), low detection limit, frequency sensitivity. Moreover, applicability this further demonstrated long‐term sensing, remote medical communication, underwater communication. Overall, findings pave way for sustainable development hydrogel‐based are self‐powered, durable, offer performance, adaptability, multi‐sensory capabilities.

Abstract Creatures, such as Venus flytrap and hummingbirds, capable of rapid predation through snap‐through transition, provide paradigms for the design soft actuators robots with fast actions. However, these artificial “snappers” usually need contact stimulations to trigger flipping. Reported here is a constrained anisotropic poly( N ‐isopropylacrylamide) hydrogel showing snapping upon light stimulation. This prepared by flow‐induced orientation nanosheets (NSs) within rectangular tube. The precursor containing gold nanoparticles immediately exposed UV photopolymerization fix ordered structure NSs. Two ends slender gel are clamped form buckle bistability nature, which snaps other side laser irradiation. Systematic experiments conducted investigate influences power intensity irradiation angle laser, well thickness height gel, on behaviors. further used kick plastic bead control switch state. Furthermore, synergetic or oscillated two buckles opposite directions realized inclined horizontal lasers, respectively. Such light‐steered hydrogels should merit designing robots, energy harvests, etc.

Aquatic actuators based on the light-to-work conversion are of paramount significance for development cutting-edge fields including robots, micromachines, and intelligent systems. Herein, we report design synthesis near-infrared light-driven hydrogel through loading with lightweight polydopamine-modified hollow glass microspheres (PDA-HGMPs) into responsive poly(N-isopropylacrylamide) (PNIPAM) hydrogels. These PDA-HGMPs can not only function as an excellent photothermal agent but also accelerate swelling/desewlling hydrogels due to their reconstruction polymer gel skeleton, which speeds up response rate actuators. The resulting actuator shows controlled movements under light illumination, complex self-propellant floating/sinking motions. As proof-of-concept demonstrations, a self-sensing robot is conceptualized by integrating PDA-HGMP-containing ultrathin miniature pressure sensor. Hopefully, this work offer some important insights research smart aquatic soft actuators, paving way potential applications in emerging micromachines
