“…Owing to the photothermal effect and heat‐to‐work ability, the carbon‐based actuators can convert the light energy into other energies. [ 30,99,36 ] For example, the ink‐PET‐acrylic actuator‐based mill was developed to convert external light energy into rotational energy using light‐triggered blades as shown in Figure a. [ 30 ] When exposed to periodic NIR light, the ink‐PET‐acrylic actuators sequentially bent and unbent to generate air flow and further drove the rotation of the light mill.…”

“…By placing the CNT/PDMS actuator on Kapton/aluminum (Al) bilayer substrate, the actuator could be employed to continuously output the electric signal upon constant light illumination (Figure 15b).

The CNT layer and Kapton layers served as the positive triboelectric layer and negative triboelectric layers, separately.…”

Recently, the optical field driving mechanism is emerging in the manipulation of small‐scale soft robots due to its remote, wireless, and selective control capabilities. Among the light‐responsive materials, carbon has exhibited great potentials as light‐driven actuators due to its good light absorption ability, thermal conductivity, and mechanical strength. Taking advantage of the carbon materials, various carbon‐based actuators are reported with efficient, fast response, and stable actuating performance. Hence, carbon‐based actuators are widely applied in robotic applications controlled by external light irradiation. This review summarizes the principle actuating mechanism of carbon‐based actuators and focuses on the analysis of the robotization and application mechanisms. The locomotion implemented by the carbon‐based actuators is discussed by analyzing the robot structure designs and light exposing approaches, accompanied with corresponding force analysis. Moreover, various applications of carbon‐based actuators are reviewed with mechanism discussion. Furthermore, the challenges, including the perspectives of the robotization and applications of carbon‐based actuators, are discussed for further development and robotic utilization of carbon‐based materials.

Untethered, light-responsive, high-stress-generating actuators based on widely-used commercial polymers are appealing for applications in soft robotics. However, the construction of actuators that are stable and reversibly responsive to low-intensity ultraviolet, visible, and infrared lights remains challenging. Here, transparent, stress-generating actuators are reported based on ultradrawn, ultrahigh molecular weight polyethylene films. The composite films have different draw ratios (30, 70, and 100) and contain a small amount of graphene in combination with ultraviolet and near-infrared-absorbing dyes. The composite actuators respond rapidly (t 0.9 < 0.8 s) to different wavelengths of light (i.e., 780, 455, and 365 nm). A maximum photoinduced stress of 35 MPa is achieved at a draw ratio of 70 under near-infrared light irradiation. The photoinduced stress increases linearly with the light intensity, indicating the transfer of light into thermally induced mechanical contraction. Moreover, the addition of additives lead to a reduction in the plastic creep rate of the drawn films compared to their nonmodified counterparts.

“…For example, the amount of the energy received can be tuned by deformation of the objects. In this manner, continuous translations or oscillations under anisotropic‐restricted conditions have been successful. To achieve fully autonomous motions without adjusting external information (e.g., direction of the stimulus source), another “quality” of molecular association is required: cooperation of asymmetric processes to enable materials to evade a static steady state …”

Light‐Driven Flipping of Azobenzene Assemblies—Sparse Crystal Structures and Responsive Behaviour to Polarised Light

For creation of autonomous microrobots, which are able to move under conditions of a constant environment and a constant energy supply, a mechanism for maintenance of mechanical motion with a capacity for self‐control is required. This requirement, known as self‐organisation, represents the ability of a system to evade equilibrium through formation of a spatio‐temporal pattern. Following our previous finding of a self‐oscillatory flipping motion of an azobenzene‐containing co‐crystal, we present here regulation of the flipping motion by a light‐receiving sensor molecule in relation to the alignment and role of azobenzene molecules in crystals. In the anisotropic structure, a specific azobenzene molecule acts as a reaction centre for the conversion of light to a mechanical function process, whereas the other molecules act as modulators for spatio‐pattern regulation. The present results demonstrate that autonomously drivable molecular materials can exhibit information‐responsive, self‐sustainable motion by incorporating stimulus‐responsive sensors.
