“…According to the working mechanism, soft sensors generally contain color, strain, capacitance, resistive, magnetic, temperature, chemical sensors, etc. For instance, Hwang et al [ 203 ] prepared a self-adhesive biocompatible soft strain sensor that could monitor the motion of human beings and the biosignals based on the combination of the self-adhesive polyurethane (SAPU) and the silver nanowires (Ag NWs). Herein, as shown in Figure 6 b, the deformation (strain) of the objects could be detected by the changing resistance.…”

The flexibility and adaptability of soft robots enable them to perform various tasks in changing environments, such as flower picking, fruit harvesting, in vivo targeted treatment, and information feedback. However, these fulfilled functions are discrepant, based on the varied working environments, driving methods, and materials. To further understand the working principle and research emphasis of soft robots, this paper summarized the current research status of soft robots from the aspects of actuating methods (e.g., humidity, temperature, PH, electricity, pressure, magnetic field, light, biological, and hybrid drive), materials (like hydrogels, shape-memory materials, and other flexible materials) and application areas (camouflage, medical devices, electrical equipment, and grippers, etc.). Finally, we provided some opinions on the technical difficulties and challenges of soft robots to comprehensively comprehend soft robots, lucubrate their applications, and improve the quality of our lives.

Wearable strain sensors are expected to meet the requirements of high sensitivity, facile fabrication, and high aesthetics to realize practical applications. However, reported sensitive strain sensors fail to exhibit multicolor due to high light absorption. Herein, a flexible strain sensor with high sensitivity and color‐exhibition ability is fabricated by half‐embedding silver nanowires (AgNWs) into dyeable thermoplastic polyurethane (TPU) films through thermal annealing. A sheet resistance of 11.5 Ω sq−1 and a transmittance above 79.9% at 550 nm is obtained for intact AgNWs/TPU films. A gauge factor of 34 797 is achieved at a tensile strain of 9%, indicating the high sensitivity for monitoring tiny movement changes. Besides, the high transparency allows color exhibition after dying. The multicolor AgNWs/TPU films are further rolled into rod‐shaped yarns and weaved with commercial yarns to form wearable colorful electronics.

Despite its potential for clean hydrogen harvesting, photoelectrochemical (PEC) water‐splitting cells face challenges in commercialization, particularly related its harvesting performance and productivity at an industrial scale. Herein, a facile fabrication method of flexible thin‐film photoanode for PEC water‐splitting to overcome these limitations, based on laser processing technologies, is proposed. Laser‐induced graphene, a carbon structure produced through direct laser writing carbonization (DLWC), plays a dual role: a flexible and stable current collector and a substrate for the hydrothermal synthesis of tungsten trioxide (WO3) nanorods (NRs). To facilitate water‐splitting, a femtosecond‐pulsed laser (fs laser) is focused on the WO3 NRs, converting their crystalline phase from pristine orthorhombic to monoclinic structure without thermal damage. With NiFe layered double hydroxide (LDH) catalyst, the flexible thin‐film photoanode exhibits good PEC performance (1.46 mA cm−2 at 1.23 VRHE) and retains ≈90% of its performance after 3000 bending cycles. With its excellent mechanical properties, the flexible photoanode can be operated in various shapes with different curvatures, enabling space‐efficient PEC water‐splitting by loading larger photoanode within a given space. This study is expected to contribute to the advancement of large‐scale solar water‐splitting cells, introducing a new approach to enhance H2/O2 production and expand its application range.
