“…However, the EMG can be regarded as a current source with a smaller internal resistance. [32,33] The curves of the output voltage and power on the external load resistance of the TENG and EMG are illustrated in Figure 3g and h, respectively. Specifically, the TENG was measured at various load resistances ranging from 100 KΩ to 240 MΩ, and the instantaneous maximum power of 4.75 μW appears at load resistance of 30 MΩ, as illustrated in Figure 3g.…”

The inexhaustible mechanical kinetic energy can be extracted from wind and flowing water. Besides, flowing water also possesses electrostatic energy owing to the triboelectric charges caused by contacting with surrounding media, such as air. Here, a rotating hybridized triboelectric nanogenerator (TENG) has been established, by comprising of a water-TENG (W-TENG), a disk-TENG (D-TENG), and an electromagnetic generator (EMG), which has been explored for simultaneously harvesting energies from flowing water and wind. The W-TENG is fabricated by wheel blades, polyvinylidene fluoride (PVDF), superhydrophobic polytetrafluoroethylene (PTFE), and aluminum to harvest the electrostatic energy. Moreover, the flowing water and wind impact on the wheel blades also causes the rotation motion of D-TENG and EMG, resulting in being converted into electricity. At the rotation speed of 200 rpm, the short circuit current of D-TENG and EMG can reach 0.4 μA and 7 mA, respectively. The open circuit voltage of W-TENG can be up to 10 V at a flowing water rate of 60 ml s À1. Besides, the hybridized NG is demonstrated to harvest water and wind energy and to act as a power source to charge a lithium battery or capacitor, which can drive LEDs, PH monitoring system, and wireless temperature and humidity sensing system. All these results show the potentials of the hybridized NG for harvesting multiple types of energies from the environment and constructing different self-powered systems.Because of the rapid energy consumption and shortage in fossil fuel, energy crisis is becoming more and more serious than ever before. For the sustainable development of modern society, harvesting different kinds of energies from ambient environment has attracted increasing attention. [1][2][3][4][5][6][7][8] Recently, the hybridized TENG has been explored as a new technology to harvest various energies, such as vibration, [9,10] air flow, [11,12] water waves, [13,14] and rotation, [15,16] which is mainly based on contact electrification effect and electrostatic induction. [17][18][19] Previously, most people used two solid materials contacting periodically to generate triboelectric charges on their interface. [20][21][22][23][24][25] Recently, triboelectric charges that are created between the interfaces of water and air are used to develop TENG widely. [26,27] The TENGs have been demonstrated a promising approach for scavenging energy from surrounding flowing medium. On the other hand, the flowing water and air has not only mechanical energy, but also electrostatic energy, which comes from the triboelectric charges in water generated during the process of contacting with pipe or air. [28] In previous reports, the researchers usually use a single energy harvesting device to grab a certain energy from flowing water and air. [29,30] However, in our demonstrations, to harvest multiple energies simultaneously, we have integrated D-TENG, W-TENG, and EMG into a hybrid energy harvester. In the W-TENG, we used PVDFand PTFE with nanostructures to enhance the forward ...

Summary Energy harvesting from pavements has been a topic of extensive research in the recent past. This domain has attracted not only the research community but also the industry and governmental authorities. The various sources exploited for energy harvesting from pavements and roadways are solar radiation, mechanical energy dissipated due to moving vehicles and pedestrians, geothermal energy, rainwater, and wind. This article presents an exhaustive and updated review of all potential means of energy harvesting from these sources. Following the introductory section, the article sequentially covers the energy harvesting methods and their research progress, materials, development of practical systems, commercial status, comparison of technologies, challenges, and concluding remarks. This study reveals that there is wide scope for further research and feasibility studies, which could lead to a wide‐spread implementation of the various technologies for energy harvesting from pavements and roads.

A single‐electrode nylon fiber‐incorporated polytetrafluoroethylene (PTFE) electret flexible film with hollow cylinder structure is developed for enhanced mechanical energy harvesting. The power is generated by the nylon fiber/PTFE electret film via bending deformations that result in charges transferring between the conductive carbon black silicone rubber (CBS) electrode and ground. The results demonstrate that the nylon fiber/PTFE electret film results in enhanced open‐circuit voltage, Voc, (about 0.45 times more) compared to a pure PTFE based on the hollow cylinder structure. With the step‐increased distance of travelling for the reported hollow cylinder structure device, more power is generated by this mechanical‐electrical energy conversion because of a greater deformation compression onto the nylon fiber/PTFE electret film. The peak of the generated short‐circuit current, ISC, and Voc based on the nylon fiber/PTFE electret film with 1 m s−2 are up to 0.35 μA and 72 V, respectively. It is also possible to light an 8 light‐emitting diode (LED) setup by finger tapping, demonstrating the good mechanical energy conversion performance of the nylon fiber/PTFE electret film. Moreover, a quick voltage response of the nylon fiber/PTFE electret film is demonstrated in several different ultrasonic environments (such as 70 kHz and 30 kHz).
