Soft robotics has undergone considerable progress driven by materials that can effectively transduce external stimuli into mechanical actuation. Here, we report the development of a photothermal-responsive hydrogel actuator with shape memory capabilities inspired adaptive locomotion sea cucumbers. This is based on cucumber peptides (SCP) and liquid metal (LM) network responsive to near-infrared (NIR) light. Upon NIR irradiation, undergoes phase transition from swollen collapsed state, resulting in controlled volumetric change. Incorporating polymer (SMP) matrix facilitates actuator's retention its deformed configuration following stimulus removal, thereby enabling intricate, multiphase transformations. SCP/LM overcomes limitations traditional hydrogels achieves good stretchability (3,000%) enough adhesion (21 kPa), exhibiting no toxicity human cells. Furthermore, exhibited significant bending complex deformation within 100 s exposure. offers new opportunities for soft biomedical applications, showcasing potential pathway incorporating next generation smart devices.

Inspired by natural organisms, actuators have shown great promise for small swimming robots. However, previous single-stimulus-driven studies limited their effectiveness in complex aquatic environments. In this study, a PINPAM/MWCNT composite actuator was developed. This can be controlled both light and chemical agents to achieve rapid drift on the water surface. It enables programmable trajectory motion water, capable of performing maneuvers such as linear translation, turning, rotation, particularly under infrared light. dovetail configurations, movement control corresponding achieved through agent actuation. The horn-shaped actuator, modeled after horns, propel transport cargos an illumination. Notably, circular spontaneously traverse U-shaped curve without external stimuli. multistimulus-responsive Marangoni significantly broadens application scope miniature actuators, paving new avenues microrobotics inspiring future advancements biomimetic robotics.

Electrochromic (EC) technology has become one of the smart technologies with most potential for development and application at this stage. Based on electrochromic devices (ECDs), shown extraordinary in fields windows, display devices, sensing systems. With optimization iteration various core components ECDs, electrolyte layer, a key component, evolved from its initial liquid state to quasi-solid solid state. As driven by increasing demands, trend indicates that all-solid-state, transparent electrolytes will likely future form layer. Recently, ionic (IL)-based field electrochromism attracted lot attention due their ability bring outstanding EC cycling stability, thermal wider operating voltage range they are regarded as new generation materials application. Although compared conventional electrolytes, IL-based have characteristics high price, viscosity, low conductivity, still considered promising applications. However, so far, there been lack comprehensive analysis reports “Research progress liquid-based devices” within field. In article, research ECDs be summarized three perspectives: liquid, quasi-solid, The directions discussed.

Thermosetting materials exhibit advantages such as dimensional stability and elasticity but lack reprocessability due to their permanently cross-linked internal structure. Introducing a reversible network endows with often compromises resilience mechanical properties. Hence, it is still significant challenge develop recyclable elastomers high traditional thermosetting remolding ability thermoplastic materials. Based on this, this work incorporates both irreversible networks into polyurethane system, constructing synergistic distinct properties achieve simultaneously. In addition, by adjusting the proportion of networks, relationship between in different was investigated, revealing effect dynamic chemical network. This provides theoretical support for design elastomer that combine thermoset

Abstract The application of self‐healing superhydrophobic triboelectric nanogenerators (TENGs) is currently limited by their poor wear resistance, which stems from reliance on nano/microscale hierarchical structures. Drawing inspiration corals, this study presents the development ultra‐wear‐resistant TENGs with sub‐zero temperature capability (USSS‐TENGs) incorporating rationally designed hydrophobic polyurethane (SFPU) and poly(vinylidene fluoride) nanoparticles (PVDF NPs) into iron foams. rigid protruding structures foams protect incorporated SFPU–PVDF NPs composites preferentially making contact bearing stress foreign objects. This innovative design enables USSS‐TENGs to maintain superhydrophobicity after repeated sandpaper abrasion, knife scratching, even car transit, demonstrating a superior resistance compared other materials. Furthermore, driven free energy minimization, migration SFPU damaged areas self‐heal at −30 °C, underwater, in vacuum. Owing outstanding superhydrophobicity, show great potential as smart roofs floor tiles, capable providing stable durable electricity generation processes such precipitation, human walking/jumping, vehicle movement. has not been previously reported for TENGs, irrespective properties.
