Carbon‐based materials are widely used as light‐driven soft actuators relying on their thermal desorption or expansion. However, applying a passive layer in such film construction greatly limits the actuating efficiency, e.g., bending amplitude and speed. In this work, a dual active layer strengthened bilayer composite film made of graphene oxide (GO)–polydopamine (PDA)–gold nanoparticles (Au NPs)/polydimethylsiloxane (PDMS) is developed. In this film, the conventional passive layer is replaced by another AuNPs‐enhanced thermal responsive layer. When applying NIR light exposure, the whole film deforms controllably resulting from the water loss in the GO–PDA–Au NPs layer and thermal expansion in the PDMS layer. Benefiting from the dual active bilayer mechanism, the thin film's actuating efficiency is dramatically improved compared with that of conventional methods. Specifically, the bending amplitude is enhanced up to 173%, and the actuating speed is improved to 3.5‐fold. The soft actuator can act as an artificial arm with high actuating strength and can be used as a wireless gripper. Moreover, the film can be designed as soft robots with various locomotion modes including linear, rolling, and steering motions. The developed composite film offers new opportunities for biomimetic soft robotics as well as future applications.

“…For the same PTL/rGO layer thickness, the bending extent is positively related to the CTE difference between PTL/rGO and polymer substrate. [ 57 ] Because both the thermal conductivity and CTE of PE are higher than those of PP, PDMS, and polyvinylidene fluoride (PVDF; Table 1), the PTL/rGO@PE bilayer film provides the best actuation performance among these samples, as the bending angle could reach 75° at a temperature of 50 °C (Figure 5a). The bending degree is also inversely proportional to the film thickness.…”

Long-distance wireless actuation indicates precise remote control over materials, sensors, and devices that are widely utilized in biomedical, defence, disaster relief, deep ocean, and outer space applications to replace human work. Unlike radio frequency (RF) control, which has low tolerance toward electromagnetic interference (EMI), light control represents a promising method to overcome EMI. Nonetheless, long-distance lightcontrolled wireless actuation able to compete with RF control has not been achieved until now due to the lack of highly light-sensitive actuator designs. Here, it is demonstrate that amyloid-like protein aggregates can organize photomodule single-layer reduced graphene oxide (rGO) into a well-defined multilayer stack to display long-distance photoactuation. The amyloid-like proteinaceous component docks the rGO layers together to form a hybrid film, which can reliably adhere onto various material surfaces with robust interfacial adhesion. The sensitive photothermal effect and a fast bending in 1 s to switch a circuit are achieved after forming the film on a plastic substrate and irradiating the bilayer film with a blue laser from 100 m away. A photoactuation distance of 50 km can be further extrapolated based on a commercial high-power laser. This study reveals the great potential of amyloid-like aggregates in remote light control of robots and devices.

“…Carbon-based materials such as carbon black, [54] carbon nanotube (CNT), [28,55] graphite, [56] graphene oxide (GO), [57][58][59] and MXene [60][61][62] are often used as light absorption layers. Polymers having large CTE such as poly(dimethylsiloxane) (PDMS), [48] polyimide (PI), [63] polycarbonate (PC), [49] biaxially oriented polypropylene (BOPP), [64] poly(vinylidene fluoride) (PVDF), [65] polyethylene (PE) [66] serve as thermal expansion layers. When a composite film is irradiated with light, each layer generates different changes in the volume and the actuation is produced due to the asymmetric volume expansion, that is, a mismatch in the CTE.…”

Photoactuators that can produce a reversible mechanical deformation under light stimuli have attracted tremendous interest in the recent years owing to the advantages of abundant availability of resources, remote and accurate control, and applicability in soft robots, sensors and biomimetic devices. In this study, the recent advances in photoactuators related to actuation mechanisms (photothermal and photochemical), fabricaton from different configurations and types of materials, and their potential applications in bionic movements are reviewed. The opportunities and challenges in this field are also discussed, such as fabricating actuators with robust mechanical properties and superior actuating performance, seeking effective actuation mechanisms, and widening the range of applications. This review provides an insight into designing high‐performance, multi‐functional photoactuators and serves as a motivation for their development in future.
