“…Wiring is generally used to power the first prototypes of these microbots for simplicity. [ 102,216 ] Power can be also delivered to these types of actuators by storing energy in micro‐batteries or supercapacitors, or by remote power transmission using inductive coupling or directing light onto onboard photovoltaic cells.

“…The power is delivered to these actuators by directing light onto photovoltaic cells on the top of the mobile microbot. [ 102,113 ] Moreover, Zhong et al [ 105 ] presented a laser‐driven microbot that utilizes two Z‐shaped silicon actuators. The movement of this microbot is induced by using a pulsing laser beam to heat up the serpentine microstructures, as shown in Figure 6i, while the driving force is controlled by tuning the beam frequency.…”

“…This microbot demonstrated movement in four directions at a speed of 10 mm min À1 . [100] U-shaped, [101] V-shaped, [102][103][104] and Z-shaped [105] electrothermal actuators are widely used in MEMS [106][107][108][109][110][111][112] due to their simple structure, large force and displacement, and compatibility with common fabrication processes. The planar displacement of these actuators limits their direct incorporation into mobile microbots requiring out-of-plane deformation of certain elements.…”

“…The integrated vehicle "RoboBee X-Wing" realized a successful takeoff and sustained untethered flights lasting for approximately 0.5 s, representing a major milestone in the development of autonomous insect-scale flying vehicles. Aiming at microfactory applications, Zhang et al 151 created a fully untethered, solar-powered micro-crawler "SolarPede" operating as a nanopositioner on planar surfaces. Four-in-series solar cells were constantly tracked by artificial light irradiation in a controlled environment and provided an output voltage of approximately 10 V under 5 suns.…”

In our day-to-day lives, advances in lightweight and flexible photovoltaics will promote a new generation of soft electronics and machines requiring high power-per-weight. Ultrathin flexible perovskite solar cells (F-PSCs) with high power-per-weight have displayed a unique potential for specific applications where lower weight, higher flexibility, and conformability are indispensable. This Review highlights the recent progress and practical applications of ultrathin and lightweight F-PSCs and demonstrates the routes toward enhanced device efficiency and improved mechanical and environmental stability concerning the choice of flexible substrates and the development of high-performance functional layers and flexible transparent electrodes. The fabrication technologies for mass production of efficient F-PSCs at large scale are then summarized, including continuous roll-to-roll methods integrated with low-temperature process. Furthermore, the practical applications focused on self-powered wearable electronic devices, solar-powered miniature unmanned aerial vehicles, and even solar modules operating in near-space are elaborated. Finally, the current challenging issues and future perspective are discussed, aiming to promote more extensive applications and commercialization processes for lightweight F-PSCs.

in underwater object manipulation and marine environment monitoring. Aquatic organisms and amphibians in nature provide great inspiration for the design and manufacture of novel underwater soft robots, which has attracted increased attention from the research community. [9][10][11][12][13] However, the controllability of the driving force still faces great challenges. Existing driving methods mainly include optical drive, [14][15][16][17] magnetic drive, [18,19] and electric drive. [20,21] Among them, optical drive has the highest controllability and tunability, so it is widely used to drive bionic soft robots in underwater operations. In addition, the use of soft smart materials increases the flexibility of bionic robots, reducing the need for heavy, and traditional rigid materials and sensing and actuation components. Most light-driven soft robots are made of liquid crystals [22][23][24][25][26][27] and hydrogels [19] that can undergo various deformations. Mechanical swing is important for converting input energy into continuous motion. Wang et al. reported a light-driven swing actuator composed of polyimide (Kapton) and azobenzene containing liquid crystal polymers. [28] The photoactive bilayer films were prepared with benzene-carboxylic acid containing monomer (M 6 BCOOH) and azobenzene-containing monomer (M 6 ABOC 2 ). When exposed to ultraviolet light, the double-layer film bends. The high modulus of the Kapton layer gives the film great resistance, so the film quickly returns to its resting position after UV light is removed. The double-layer strip exhibits mechanical swing behavior under continuous UV irradiation. Ma et al. also made a light-driven swimmer based on the above double-layer structure. [29] The swimmer bends quickly under UV light and recovers immediately after removing the light. When placed on a liquid surface, swimmers beat the liquid rhythmically, constantly propelling themselves forward.Snake is a kind of amphibian. Despite its simple body structure, it can realize a variety of locomotion forms, such as concertina locomotion and serpentine locomotion, to adapt to the changeable environment. So far, many researchers have studied the movement of snakes. For example, Yang et al. reported a snake-like biomimetic soft robot synthesized by three layers of graphene oxide (GO) and polydopamine. [13,[30][31][32][33] The soft material is capable of bidirectional deformation when near-infrared many researchers have studied the movement of snakes.
