“…The energy-harvesting outcomes of a large-area monolayer MoS 2 film reached ∼0.4 V and ∼40.7 nA with optimal domain configurations relative to the position of the interdigitated electrodes [129]. Applications using inorganic nanostructures have been extended to self-powered wearable systems with diverse functionalities, which may also be suitable for artificial intelligence and machine learning systems interfacing with human motions and activities [130,131]. Nanofiber-based composite generators have been extensively investigated as patches or woven fabrics for driving low-power devices or converting physical motion into electrical signals.…”

Ambient energy harvesting has great potential to contribute to sustainable development and address growing environmental challenges. Converting waste energy from energy-intensive processes and systems (e.g., combustion engines and furnaces) is crucial to reducing their environmental impact and achieving net-zero emissions. Compact energy harvesters will also be key to powering the exponentially growing smart devices ecosystem that is part of the Internet of Things, thus enabling futuristic applications that can improve our quality of life (e.g., smart homes, smart cities, smart manufacturing, and smart healthcare). To achieve these goals, innovative materials are needed to efficiently convert ambient energy into electricity through various physical mechanisms, such as the photovoltaic effect, thermoelectricity, piezoelectricity, triboelectricity, and electromagnetic power transfer. By bringing together the perspectives of experts in various types of energy harvesting materials, this Roadmap provides extensive insights into recent advances and present challenges in the field. Additionally, the Roadmap analyzes the key performance metrics of these technologies in relation to their ultimate energy conversion limits. Building on these insights, the Roadmap outlines promising directions for future research to fully harness the potential of energy harvesting materials for green energy anytime, anywhere.

The development of multivariate nanoreinforced composites requires available distinguishable visualization approaches to reveal structure–activity relationships. Here, a confined fluorescent detection strategy is employed to cleverly avoid the adverse interference of fluorescence resonance energy transfer (FRET), enabling the distinguishable visualization of multivariate nanoparticles in composites. The strategy relies on rational design and successful synthesis of multivariate nanoparticles with a distinct fluorescent probe labeled, namely, f-SiO2, f-MWCNTs, and f-GO. Thus, the large-scale 3D dispersion of multivariate nanoparticles was visualized by confining detection of non-overlapping fluorescence emission signals and subsequently was quantitatively analyzed through theoretical calculation. Moreover, the emergence of pseudo-color fluorescent dots suggested that the multivariate nanoparticles constructed a micro-interpenetrating structure that encouraged the dispersion of themselves. This conclusion had been supported by both microstructure characterization and macromechanical performance. It was demonstrated that the proposed distinguishable visualization method opened viable opportunities and inspirations for the design and controllable preparation of nanocomposites.
