“…Most current studies investigating materials suitable for tiny energy devices, explore a range of materials to create on-board energy systems and benchmark material performance (Level 0). Though these findings offer a reservoir of possibilities, [16][17][18][19] their seamless translation into device performance remains elusive, primarily due to the isolation of this material development from the intricate integration processes essential for microrobotics.…”

Energy serves as the foundational element for all active functions within microrobots. Harvesting devices, such as photovoltaic cells and coils, play a crucial role in converting diverse forms of energy into electricity, while energy storage devices enable uninterrupted operation and liberate microrobots from dependence on external sources. Despite the evident importance of energy, there exists a significant disconnect between the development of energy devices and their integration into microrobotic systems, hampering the deployment of microrobots across diverse fields from agriculture to microsurgery. Here, for transcending the “material for material's sake” focus on simple generic metrics for material optimization, such as energy density, advocating attention to the higher tier transformation of material metrics that determine device‐level performance and so make a meaningful contribution to microrobotic technology is argued. Appropriate metrics for microrobotic swarms challenge the stereotype that tiny energy supplies are impractical; instead, swarms simplify individual microrobotic functions, reducing single energy supply requirements and utilizing swarm energy distribution and management. In addition to essential evaluations of the environmental and social impacts of intelligent microrobotic swarms for their safe and beneficial implementation, research targeting these higher‐tier metrics is crucial to connecting energy material research and microrobot developments effectively.

“…In response to the increasing energy demand and the global challenge in energy crisis and environmental issues, harvesting electric energy from renewable and green sources is both important and sustainable. , Up to date, various electricity generation technologies from environmental energy have been developed, such as photovoltaic electricity generation, thermoelectric generation, triboelectric generation, and moisture-induced electricity generation . However, these electricity harvesting technologies need external triggers, and the generated electricity is pulsive.…”

In this study, the electric energy harvesting capability of the hierarchical pore gradient silica aerogel (HPSA) is demonstrated due to its unique porous structure and inherent hydroxyl groups on the surface. Taking advantage of the positively charged surface of unwashed HPSA credited by the preparation strategy, poly(4-styrene sulfonic acid) (PSS) can be spontaneously adsorbed onto unwashed HPSA and shows gradient distribution due to the pore-gradient structure of HPSA. By virtue of the gradient distribution and the stronger ionization of PSS, PSS-modified HPSA (PSS−HPSA) shows enhanced electricity generation performance from natural water evaporation with an average output voltage of 0.77 V on an individual device. The water evaporation-induced electricity property of PSS−HPSA can be maintained in the presence of a low concentration of salt. The desirable salt resistance capability benefits from the unique 3D hierarchical porous structure of HPSA which ensures rapid water replenishment so as to effectively avoid the salt accumulation. The HPSA-based devices with the advantages of unique porous structure, easy functionalization, good physicochemical stability, good salt resistance capability, and eco-friendliness show great potential as water evaporation-induced electricity generators.

Lightweight and bendy plastic‐based perovskite solar cells (PSCs) are considered strong emerging rivals to the rigid heavy‐block photovoltaics made of conventional crystalline‐silicon. To further increase the competitiveness of these devices, the research community is nowadays searching for compatible, effective and scalable strategies to achieve efficiencies of >20%, while their development using lower‐cost and greener materials is also increasingly investigated. From the precursor solutions and prenucleation state of perovskites to the fully crystallized materials, this disclosure provides key findings that benefit fundamental understanding for streamlining antisolvent quenching methods toward the development of high‐performance and stable flexible‐plastic PSCs under ambient atmospheric conditions. Evidencing the importance of the concurrent consideration of a series of antisolvent physical properties for a group of primary and secondary monohydric alcohols, a breakthrough achievement is attained. Mirror‐like, pinhole‐free, monolayered vertically‐aligned (high‐aspect‐ratio) grained and mechanically‐robust ambient‐air‐processed perovskite structures are developed using 2‐butanol as a non‐toxic and benign‐to‐plastics (evidenced by nano‐mechanics) antisolvent alternative to the reference chlorobenzene. To this end, a new literature record of 20.09% for scalable carbon‐based flexible PSCs is achieved (power‐to‐weight performance 1.05 Wg−1, at 190 gm−2), also demonstrating highly‐robust unencapsulated devices under the ISOS‐D‐1 protocol conditions (T85 >1000 h) and bending fatigue (T80(5‐mm‐radius) >5000 bending cycles).
