“…A summary of the output characteristics of some of these devices under standard operating conditions is shown in Figure . Because carbon‐based materials have a high conversion efficiency, they account for the majority of the active materials used in water‐enabled electricity generation systems, with the focus being on graphene‐based materials, [ 15,22,24,36–39,44–46,48,55,66,68–81 ] CNPs and carbon nanofibers (CNFs), [ 13,14,16,25,53,64,67,82–91 ] polymers, [ 23,31,38,66,83,89,92–99 ] and biomaterials. [ 26,30,69,74,90,91,100–102 ] Solid oxide materials [ 10,12,13,19,20,54,64,103–106 ] are also favored as they are easily fabricated into an active layer and are stable even in harsh environments.…”

Harvesting energy from the environment offers many opportunities for the generation of clean power from self‐sustained systems and provides great promise for ameliorating the growing threat of the global environmental issues and the energy crisis. Ambient moisture and natural water sources have attracted huge research interest in the field of energy harvesting and conversion due to easy access, good sustainability, and the ubiquity of water on Earth. Taking advantage of the active interaction between water molecules and solid interfaces, various functional materials have been demonstrated to harvest energy and generate useable amounts of electrical power from water. In this review, some perspective on the development of water‐enabled electricity generation is given. The current preferred methods for water‐enabled electricity generation and relevant functional materials are summarized. Also, how the development of new materials and systems has led to significant improvements in the electrical power output reported for these devices is discussed. Then, some recent advances that have resulted in dramatic increases in the electrical output available from water‐enabled electrical generators (WEEGs) is discussed. Finally, some future trends in the development of WEEGs are outlined, and how this may result in practical applications and commercialization of these devices is shown.

“…Using cellulose aerogel as a TENG material, a very high voltage of 60.6 V, a current of 7.7 A, and a power density of 2.33 W/m 2 were achieved, bringing fresh insights into the investigation of porous materials with variable triboelectric polarities for high performance TENGs. Using PEDOT:PSS/graphene oxide composite aerogel sponges for TENG, the PEDOT:PSS network were bonded to the surface of the GO with abundant halogen functional groups [28]. The curving energy of the graphene surface is altered by these halogen functional groups and aromatic hydrocarbons.…”

With the rapid growth of numerous portable electronics, it is critical to develop high-performance, lightweight, and environmentally sustainable energy generation and power supply systems. The flexible nanogenerators, including piezoelectric nanogenerators (PENG) and triboelectric nanogenerators (TENG), are currently viable candidates for combination with personal devices and wireless sensors to achieve sustained energy for long-term working circumstances due to their great mechanical qualities, superior environmental adaptability, and outstanding energy-harvesting performance. Conductive materials for electrode as the critical component in nanogenerators, have been intensively investigated to optimize their performance and avoid high-cost and time-consuming manufacture processing. Recently, because of their low cost, large-scale production, simple synthesis procedures, and controlled electrical conductivity, conducting polymers (CPs) have been utilized in a wide range of scientific domains. CPs have also become increasingly significant in nanogenerators. In this review, we summarize the recent advances on CP-based PENG and TENG for biomechanical energy harvesting. A thorough overview of recent advancements and development of CP-based nanogenerators with various configurations are presented and prospects of scientific and technological challenges from performance to potential applications are discussed.

Moisture is a ubiquitous and clean resource in nature, which continuously diffuses in the atmosphere and demonstrates huge chemical potential energy that is difficult to be utilized. Recently, the generation of power from interactions between graphene and gaseous water molecules in moisture has triggered great research interest that could provide a novel energy conversion system for our society. graphene-based assemblies have been considered as ideal platforms for moist-electric generation (MEG) in many studies, because of the abundant of functional groups, controllable microstructure and diverse macro morphologies. Therefore, in this short review, we will first state the preparation techniques of graphene-based assemblies for MEG. Then, the fundamental mechanisms of MEG are discussed and the latest advances on graphene MEG are reviewed. Finally, an overview of the current challenges and future development trends in graphene MEG is provided.
