“…The carrying capacity has also been exceedingly enhanced in 2022, being reported to uphold loads more than 4600 times of the actuator’s own weight. The composite film created by depositing CNTs onto a liquid crystal elastomer fiber displayed excellent photo-actuating behavior, and therefore it can be employed as artificial muscles [ 212 ].…”

In recent years, the emergence of low-dimensional carbon-based materials, such as carbon dots, carbon nanotubes, and graphene, together with the advances in materials science, have greatly enriched the variety of flexible and stretchable electronic devices. Compared with conventional rigid devices, these soft robotic sensors and actuators exhibit remarkable advantages in terms of their biocompatibility, portability, power efficiency, and wearability, thus creating myriad possibilities of novel wearable and implantable tactile sensors, as well as micro-/nano-soft actuation systems. Interestingly, not only are carbon-based materials ideal constituents for photodetectors, gas, thermal, triboelectric sensors due to their geometry and extraordinary sensitivity to various external stimuli, but they also provide significantly more precise manipulation of the actuators than conventional centimeter-scale pneumatic and hydraulic robotic actuators, at a molecular level. In this review, we summarize recent progress on state-of-the-art flexible and stretchable carbon-based sensors and actuators that have creatively added to the development of biomedicine, nanoscience, materials science, as well as soft robotics. In the end, we propose the future potential of carbon-based materials for biomedical and soft robotic applications.

“…Upon removing the light source, the actuators cool quickly and the deformed shape reverses. To date, various photothermal materials like carbon nanotubes, 37,38 gold nanoparticles, 14 graphene 39 and emerging MXene sheets 23 have been functioned for developing homogenous LCE mixtures with stable NIR-photothermal actuation ability. However, some notable shortcomings related to these inorganic fillers, like complex and multi-step surface chemicalmodification process for their compatibilities with polymer matrices, high filling concentration (1-10 wt%) and opaque color, also exist in the development of homogenous LCE mixtures and limits their further applications.…”

“…17,18 Generally, there are three kinds of light-driven smart materials via light-mediated molecular conformation, 19 light-triggered physical reaction, 20,21 and combination of the photothermal effect and thermally triggered morphing. [22][23][24][25] These materials are mainly homogenous in the material design. However, the internal stress due to the optical absorption difference along the thickness is very common in homogeneous materials but not to be neglected for actuators.…”
