“…Dielectric materials with high tribo‐charge affinity can enhance the output performance of TENG. [ 26 ] Initially, we selected various dielectric material pairs to fabricate FTENGs and evaluated their performance (Figure 1e). Experimental results demonstrate that TENG, employing PTFE balls as negative tribo‐material and PDMS as positive friction material, exhibits superior output performance.…”

Triboelectric nanogenerators (TENGs) present a great potential approach for low‐frequency blue energy harvesting due to their unique advantages, however, omnidirectional wave energy harvesting remains challenging in complex marine environments. Herein, an omnidirectional multi‐track spherical structure TENG (OMS‐TENG) based on eight‐track fan type TENG (FTENG) is developed for harvesting low‐frequency ocean energy. The diameter and number of PTFE balls are optimized theoretically for boosting individual FTENG output and verified experimentally. The connection mode between different tracks and layers of OMS‐TENG is further investigated for efficient omnidirectional ocean energy harvesting. The motion parameters including translation and oscillation on electrical output performances of OMS‐TENG are systematically investigated and optimized. OMS‐TENG has proved to be an efficient device for harvesting omnidirectional wave energy with excellent stability and durability in complex marine environments. The maximum instantaneous power of 1270 µW can be obtained by individual OMS‐TENG. This work provides an effective approach toward omnidirectional ocean energy harvesting and important guidance for designing sustainable energy harvester.

With the rapid development of industry and information technology, rough challenges have been put forward for the traditional sensor technology to meet the increasingly complex and diverse application demands in actual production and daily life, and the widely distributed sensor network also faces complex power supply and maintenance problems. As a new energy conversion technology, triboelectric nanogenerators (TENGs) based on triboelectrification and electrostatic induction effect can respond to the weak mechanical stimuli in the surrounding environment and generate corresponding electrical signals to realize the sensing function without external power supply. In addition, TENGs have the advantages of wide selection of fabrication materials, flexible and diverse fundamental modes, which can be customized for different applications and realize different sensing functions. In recent years, triboelectric sensors based on TENGs have developed rapidly, and researchers have developed variable triboelectric sensors for different application scenarios. In this paper, the developed triboelectric sensos have been classified into different categories, the advanced strategy to prepare advanced triboelectric materials and technology used for manufacturing integration have been introduced. This work summarizes the main applications of triboelectric sensors and put forward the current challenges, so as to provide guidance and instructions for the future development of triboelectric sensors.

“…[ 100 ] The theory of TENG is based on Maxwell's displacement current. [ 101 , 102 , 103 ] In contrast to the generally observed current conveyed by free electrons, displacement current is the current generated by time‐varying (vacuum or medium) electric fields. In the year 2017, Professor Wang made a significant contribution by expanding the concept of displacement current.…”

The emergence of digital twins has ushered in a new era in civil engineering with a focus on achieving sustainable energy supply, real‐time sensing, and rapid warning systems. These key development goals mean the arrival of Civil Engineering 4.0.The advent of triboelectric nanogenerators (TENGs) demonstrates the feasibility of energy harvesting and self‐powered sensing. This review aims to provide a comprehensive analysis of the fundamental elements comprising civil infrastructure, encompassing various structures such as buildings, pavements, rail tracks, bridges, tunnels, and ports. First, an elaboration is provided on smart engineering structures with digital twins. Following that, the paper examines the impact of using TENG‐enabled strategies on smart civil infrastructure through the integration of materials and structures. The various infrastructures provided by TENGs have been analyzed to identify the key research interest. These areas encompass a wide range of civil infrastructure characteristics, including safety, efficiency, energy conservation, and other related themes. The challenges and future perspectives of TENG‐enabled smart civil infrastructure are briefly discussed in the final section. In conclusion, it is conceivable that in the near future, there will be a proliferation of smart civil infrastructure accompanied by sustainable and comprehensive smart services.
