“…To enhance the durability of the TENG, a pendulum inspired TENG (P-TENG) was designed by Lin et al, which could not only improve the output frequency but also boost the energy harvesting efficiency through converting the impact kinetic energy into potential energy. 136 Figure 10K shows the structural diagram of the P-TENG, consisting of a pendulum triboelectric layer, an electrode layer, and thin stripes. The fundamental working principle of the P-TENG is schematically depicted in Figure 10l.…”

“…Since it is not possible to ensure that all the D‐TENG units work in the same phase, rectifiers are required to connect the units to form a D‐TENG network (Figure 5b). [ 34 ] To explore the output behavior of the D‐TENG network with several units, the output current of the D‐TENG network was tested based on the number of integrated units, as shown in Figure 5c. Evidently, the output current of the D‐TENG network increases linearly as the number of units increases, and the maximum current is 2.8 µA for seven D‐TENG units.…”

The high‐efficiency conversion of water drop mechanical energy into electrical energy has always been an urgent issue in the development and utilization of raindrop energy. In this work, a novel drum‐like triboelectric nanogenerator (D‐TENG) with robust self‐cleaning superhydrophobic features is developed to harvest water drop energy. An elastic superhydrophobic cellulose paper is created by spray‐coating nanofumed silica dispersed in a thermoplastic elastomer solution, followed by treatment with triethoxy‐1H,1H,2H,2H‐tridecafluoro‐n‐octylsilane. When raindrops hit the D‐TENG surface, the superhydrophobic cellulose paper will vibrate and periodic contact and separation with polytetrafluoroethylene will occur to generate electricity. The results demonstrate that when a 6 mm water drop falls from a height of 2.5 m and hits the D‐TENG, the generated voltage output can reach a peak of 21.6 V and charge transfer of 10 nC. The output power of the D‐TENG can reach 16 µW per droplet, which is more than 13.3 times that generated from the previous TENGs based on the electrostatic induction of water droplets. These results indicate that the superhydrophobic cellulose paper‐based D‐TENG is potentially a strong candidate for harvesting energy from raindrops, thereby making it a promising sustainable energy source for next‐generation electronics.

“…This application has confirmed the technical feasibility of the WWEH-based self-powered wireless sensor networks for environmental monitoring. Figure 17g shows a self-powered wireless forest fire warning system based on a pendulum-inspired TENG that harvests wind energy [184]. The pendulum structure not only boosts the output frequency but also significantly enhances the energy harvesting efficiency through transforming impact kinetic energy into potential energy.…”

Sensor networks are essential for the development of the Internet of Things and the smart city. A general sensor, especially a mobile sensor, has to be driven by a power unit. When considering the high mobility, wide distribution and wireless operation of the sensors, their sustainable operation remains a critical challenge owing to the limited lifetime of an energy storage unit. In 2006, Wang proposed the concept of self-powered sensors/system, which harvests ambient energy to continuously drive a sensor without the use of an external power source. Based on the piezoelectric nanogenerator (PENG) and triboelectric nanogenerator (TENG), extensive studies have focused on self-powered sensors. TENG and PENG, as effective mechanical-to-electricity energy conversion technologies, have been used not only as power sources but also as active sensing devices in many application fields, including physical sensors, wearable devices, biomedical and health care, human–machine interface, chemical and environmental monitoring, smart traffic, smart cities, robotics, and fiber and fabric sensors. In this review, we systematically summarize the progress made by TENG and PENG in those application fields. A perspective will be given about the future of self-powered sensors.
