“…At the beginning of 2022, Nie and co-workers came up with a facile and effective methodology through which a novel selfhealable dielectric elastomer was prepared, exhibiting high stretchability, good dielectric properties, large actuation, and an outstanding self-repair ability against mechanical and electrical damage. 345 The dielectric elastomeric system was achieved by blending poly(vinylidene fluoride-co-hexafluoropropylene) (P-(VDF-HFP)) with increasing quantities (up to 20 wt %) of FS30, a well-known fluorosurfactant. The morphology, chemical structure and composition was successfully confirmed by means of SEM, FTIR, and elemental mapping.…”

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.

“…shape memory materials [16][17][18][19][20], etc. However, electromagnetic actuators, pneumatic actuators, and microliter combustion actuators have heavy systems and bulky volumes, which are not conducive to improving the resolution of braille; the piezoelectric actuators and PVDF have relatively small tactile displacement outputs, which limits the readability of braille; IPMC has a short working time in air [21,22]; the driving voltage of the dielectric elastomer is high (several kilovolts), endangering the safety of operators [23][24][25][26][27]; the response speed of shape memory materials is slow [28][29][30]. Hence, novel actuators need to be proposed to solve the above problems.…”

Braille displays are a class of human-computer interaction electromechanical devices that display dynamic braille through an array of actuators. However, existing actuators for braille displays suffer from issues such as bulky size, heavy weight, and small tactile displacement, leading to difficulties in improving their resolution and readability. To address the above issues, we developed a novel electroactive artificial muscle actuator and applied it to braille displays. The novel actuator consists of a surface-structured PVC gel and planar electrodes. To investigate the effect of surface structure on the performance of novel PVC gel actuators, four types of surface-structured PVC gels were fabricated by a casting process, and their actuation performance was tested. The results show that the conical and frustum conical array structures are more favorable for improving the displacement of novel PVC gel actuators, while the cylindrical and quadrangular array structures are more favorable for improving their recovery forces. We observed both surface structure and dynamic electrical actuation, suggesting that the actuation of the novel actuator is mainly caused by the deformation of the surface structure of the array. We also analyzed electrowetting effects in PVC gels using the Lippmann-Young equation, to explain the differences in the performance of surface-structured PVC gels with different contact angles. Moreover, six multilayer actuators composed of PVC gels with a conical surface array structure are applied to the braille display unit to display the braille digits from 0 to 9. It has been shown that the novel PVC gel actuator has excellent mechanical properties, which makes it an ideal solution for braille displays.
