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.

“…Yu et al [ 51 ] proposed a nanowire structure film TENG as an acceleratio sensor to detect the state of health of bridges. Zhang et al [ 52 ] demonstrated an in‐situ sensor on the basis of TENG to obtain measurements for the quantification of the strain of a bridge. Currently, the TENG‐related study that can effectively collect the low‐frequency random vibration of the bridge cable is lacking.…”

The stay cable is susceptible to external loads resulting in vibration. Aiming at the large variation of vibration amplitude of stay cable, a damping structured triboelectric nanogenerator (DS‐TENG) for stay cables vibration energy graded harvesting is proposed. The DS‐TENG can not only achieve the graded harvesting of vibration energy, but also provide adjustable additional damping for the cable by utilizing the friction force generated by the wavy center pole and the moving block. With a vibration magnitude of 24 mm as the limit, the DS‐TENG is divided into two order states. The experimental results suggest that the output of the DS‐TENG is 250 V and 42 μA of unit I, and 440 V and 110 μA of unit II. Application demonstration experiments show that the DS‐TENG can power a thermohygrometer and can generate a maximum additional damping force of 91.8 N. In the second‐order state, the DS‐TENG illuminates twice as many light‐emitting diodes as it does in the first‐order state. And experiments demonstrate the ability of the DS‐TENG to operate in harsh environments such as bridges. This work provides important guidance and reference for vibration energy harvesting and cable vibration reduction of stay cable bridges.

“…[12] The output signals transmitted by the TENG show outstanding performance in detecting mechanical changes [13] such as rotation, [14][15][16] vibration, [17][18][19][20] displacement, [21][22][23] and multifunctional motion. [24][25][26] Based on these advantages, researchers have carried out preliminary investigations in the field of bridge health monitoring, [27][28][29] including beam pier settlement, [30] beam body deformation, [31] and bridge vibration. [32,33] The electromagnetic generator (EMG) is often used in the design of power generation and sensing equipment in combination with TENG due to its excellent characteristics such as strong current and stable output.…”

Monitoring and controlling the vibration of bridge cables can maintain the health of the bridge structure and prolong the service life. This work proposes a novel self‐powered intelligent damper (SID) integrated triboelectric‐electromagnetic hybrid unit for vibration in situ monitoring of stay cables. Among them, the sensing function of the SID is realized by an arched membrane triboelectric nanogenerator (AM‐TENG), and the energy harvesting is realized by a three‐phase electromagnetic generator (TP‐EMG). The working principle and performance are investigated. Rotating and linear experimental platforms are built to verify the SID's low‐frequency (0.25–1.50 Hz) performance, including sensing, power generation, and vibration reduction. The experimental result indicates that the fitting vibration speed coefficient of the bridge cable with the AM‐TENG signal frequency is 0.990. In addition, the TP‐EMG achieves a peak power of 1.21 W. At 0.1 A power supply, the SID can output a damping force of 50 N. Finally, an experimental system is constructed to verify the viability of the SID in bridge cable vibration monitoring and vibration reduction. This work provides a feasible solution for further optimizing the bridge structure health monitoring and maintenance system.
