“…By combining lithographic techniques with buckling‐guided assembly, microscale TFFAs (lateral dimensions, characteristic feature sizes, and thicknesses are as small as ≈500, 10, and 5 μm, respectively) with complex 3D configurations could be realized. [ 40 ] Recently, using such 3D SMP‐based TFFAs, Ji et al [ 41 ] fabricated reconfigurable 3D mesofliers capable of large bending deformations, with a fast response (e.g., ≈1 s).…”

Human‐like and creature‐like systems are one of the most representative imaginary blueprints of future robots. To fulfill this blueprint, the development of high‐performance actuators across different length scales is indispensable. Owing to their mechanical compliance and conformability to curvy surfaces of living organisms, flexible actuators have emerged as an essential direction of next‐generation actuators. This review focuses on thin‐film‐shaped flexible actuators (TFFAs), a rising family of flexible actuators, aiming to provide an overview of the state‐of‐art status in this exciting direction. The designs, manufacturing, and mechanisms of various TFFAs are summarized, according to their key composing materials/mechanisms, including, for example, nanomaterials, liquid crystal elastomers, shape memory polymers/alloys, hydrogels, biohybrids, and other mechanisms/materials. The representative applications of TFFAs are introduced, ranging from biomedical uses, robots for environment explorations, to haptic interfaces and reconfigurable electronics. Finally, the grand challenges and open opportunities are discussed in detail.

“…3D assembly (e.g., rolling, folding, curving, and buckling) has received extensive attention in recent years [ 100 , 101 , 102 ]. Transforming 2D thin films into complex 3D structures could be compatible with well-established planar micromanufacturing technologies and rearrange function materials/components in a 3D layout to expand novel functions, enhance performance, and improve integration.…”

Multifunctional wearable sensors and systems are of growing interest over the past decades because of real-time health monitoring and disease diagnosis capability. Owing to the tremendous efforts of scientists, wearable sensors and systems with attractive advantages such as flexibility, comfort, and long-term stability have been developed, which are widely used in temperature monitoring, pulse wave detection, gait pattern analysis, etc. Due to the complexity of human physiological signals, it is necessary to measure multiple physiological information simultaneously to evaluate human health comprehensively. This review summarizes the recent advances in multifunctional wearable sensors, including single sensors with various functions, planar integrated sensors, three-dimensional assembled sensors, and stacked integrated sensors. The design strategy, manufacturing method, and potential application of each type of sensor are discussed. Finally, we offer an outlook on future developments and provide perspectives on the remaining challenges and opportunities of wearable multifunctional sensing technology.

Chemical Marangoni propulsion enables dynamic and untethered motion by generating surface tension gradient through chemical release, thereby having great potential for the development of insect-scale self-propelled robots. However, as the release and diffusion of chemical "fuels" are commonly uncontrollable, the Marangoni propulsion is unstable, thereby restricting robotic applications. Herein, the laser fabrication of superhydrophobic swimming robots to develop controllable Marangoni propulsion based on a photothermal composite of graphene and polydimethylsiloxane is reported. By combining the microfluidic channels with photothermal air chambers, a light-triggered switch that can control the release of chemical "fuels" is proposed. Furthermore, a superhydrophobic surface is fabricated on the swimming robot by laser treatment, which reduced water resistance and promoted propulsion. On-demand actuation and swimming route planning are realized by programming the alcohol/air segments in the releasing channels, on-demand actuation and swimming route planning have been realized. As a proof-of-concept, a Marangoni swimming robot equipped with a miniature digital camera is used in an actual environment. Therefore, this study is expected to advance the practical applications of the chemical Marangoni effect in swimming robots.
