“…Very recently, Meng et al reported a bioinspired material which combines fluorescence color-tunable, shape-memory, and self-healing properties triggered by temperature. 311 In addition, this material showed outstanding tensile properties with a breaking tensile value of 1600%. In this work, the fluorescence color change was given by the photophysical effect known as aggregation-induced emission (AIE), where the luminescence of aggregation-induced emission agents (AIEgens) is activated by the formation of aggregates.…”

Natural evolution has provided multicellular organisms with sophisticated functionalities and repair mechanisms for surviving and preserve their functions after an injury and/or infection. In this context, biological systems have inspired material scientists over decades to design and fabricate both self-healing polymeric materials and soft actuators with remarkable performance. The latter are capable of modifying their shape in response to environmental changes, such as temperature, pH, light, electrical/magnetic field, chemical additives, etc. In this review, we focus on the fusion of both types of materials, affording new systems with the potential to revolutionize almost every aspect of our modern life, from healthcare to environmental remediation and energy. The integration of stimuli-triggered selfhealing properties into polymeric soft actuators endow environmental friendliness, cost-saving, enhanced safety, and lifespan of functional materials. We discuss the details of the most remarkable examples of self-healing soft actuators that display a macroscopic movement under specific stimuli. The discussion includes key experimental data, potential limitations, and mechanistic insights. Finally, we include a general table providing at first glance information about the nature of the external stimuli, conditions for self-healing and actuation, key information about the driving forces behind both phenomena, and the most important features of the achieved movement.

“…4 Moreover, the introduction of specific metal ions or metal complexes can simultaneously endow the self-healing material with additional functions, such as luminescence, stimulus-responsive and magnetic properties. 5,6 Of the numerous metal ions or complexes, lanthanide ions (Ln 3+ ) (and Ln 3+ -complexes) are highly interesting owing to their unique photoluminescence properties, including narrow-band emission, long decay times, and large stock's shifts. 7 Thus, the combination of self-healing properties and the superior photoluminescence properties of Ln 3+ -complexes will inevitably produce many new possibilities.…”

Soft actuators have garnered substantial attention in current years in view of their potential appliances in diverse domains like robotics, biomedical devices, and biomimetic systems. These actuators mimic the natural movements of living organisms, aiming to attain enhanced flexibility, adaptability, and versatility. On the other hand, angle-independent structural color has been achieved through innovative design strategies and engineering approaches. By carefully controlling the size, shape, and arrangement of nanostructures, researchers have been able to create materials exhibiting consistent colors regardless of the viewing angle. One promising class of materials that holds great potential for bioinspired soft actuators is MXenes in view of their exceptional mechanical, electrical, and optical properties. The integration of MXenes for bioinspired soft actuators with angle-independent structural color offers exciting possibilities. Overcoming material compatibility issues, improving color reproducibility, scalability, durability, power supply efficiency, and cost-effectiveness will play vital roles in advancing these technologies. This perspective appraises the development of bioinspired MXene-centered soft actuators with angle-independent structural color in soft robotics.
