“…The rolling of the freestanding Nylon ball on the Kapton film generated opposite charges on their surfaces (state i), and as the ball rolled from the left to the right, the electric potential of the two electrodes changed, inducing an output voltage and current when connected to the external circuit (state ii). [130] UV treatment of the silicone ball and mixture of polyformaldehyde (POM) particles into the silicone dielectric layer greatly enhanced the output performance, as indicated by the comparison study in Figure 13f. As the ball moved backward, an opposite current flow was induced until it reached the left electrode again.…”

As the world is marching into the era of the internet of things (IoTs) and artificial intelligence, the most vital development for hardware is a multifunctional array of sensing systems, which forms the foundation of the fourth industrial revolution toward an intelligent world. Given the need for mobility of these multitudes of sensors, the success of the IoTs calls for distributed energy sources, which can be provided by solar, thermal, wind, and mechanical triggering/vibrations. The triboelectric nanogenerator (TENG) for mechanical energy harvesting developed by Z.L. Wang's group is one of the best choices for this energy for the new era, since triboelectrification is a universal and ubiquitous effect with an abundant choice of materials. The development of self‐powered active sensors enabled by TENGs is revolutionary compared to externally powered passive sensors, similar to the advance from wired to wireless communication. In this paper, the fundamental theory, experiments, and applications of TENGs are reviewed as a foundation of the energy for the new era with four major application fields: micro/nano power sources, self‐powered sensors, large‐scale blue energy, and direct high‐voltage power sources. A roadmap is proposed for the research and commercialization of TENG in the next 10 years.

“…Triboelectric effect, a contact-induced electrification phenomenon occurs ubiquitously in our daily life, is normally regarded as a negative effect. Since 2012, the invention of TENG has made full utilization of this effect, converting mechanical energy in the ambient environment into electricity, [88][89][90] such as vibrations, [91][92][93] wind, 94,95 water waves, 96,97 and human motions. [98][99][100][101] Owing to various advantages of TENG, such as a broad range of material selection, simplicity of structure design, cost-effectiveness, and high output, TENG has been intensively explored in the application of flexible power sources and self-powered environmental sensors, which exhibits the great potential for the future development of wearable electronics and the Internet of Things.…”

Flow-induced energy harvesting has attracted more and more attention among researchers in both fields of the wind and the fluid. Piezoelectric energy harvesters and triboelectric nanogenerators are exploited to obtain superior performance and sustainability, and the electromagnetic conversion has been continuously improved in the meantime. Aiming at different circumstances, researchers have designed, manufactured, and tested a variety of energy harvesters. In this paper, we analyze the state-of-the-art energy harvesting techniques and categorize them based on the working environment, application targets, and energy conversion mechanisms. The trend of research endeavors is analyzed, and the advantages, existing problems of energy harvesters, and corresponding solutions of energy harvesters are assessed.Energies 2019, 12, 2184 2 of 22 pose a potential threat to human health. The environmental threat is more obvious for one-off batteries, which are not intended for replacement and recycling, resulting in appreciable pollution problems [13]. Harvesting energy from the environment instead of carrying a chemical battery around is safer, undoubtedly, for both humans and the nature. Safety and universality make environmental energy harvesting an attractive topic. Relatively speaking, energy harvesting has advantages, as follows: (a) Battery-less operations are feasible, (b) embedded systems are easy to wire, (c) the infrastructure is easy to retrofit, (d) labor is saved, or "fit and forget" [14], and (e) the equipment is lightweight. Some long-term monitor systems with low power consumption, such as sensors for building structure health detection, body information collection, and low-energy self-maintenance systems [15] usually need long-term stable energy supply. In practical applications, ocean climate detectors have an option to take advantage of the ocean by using tidal energy or wave energy, and bridge safety monitors can be recharged by wind flow to suit local conditions. Thus, ubiquitous flow energy provides a good energy harvesting option toward self-powered systems.Energy harvesting from flow environments flourishes with the development of the energy industry along the general trend. Various forms of flow energy, such as wave, tidal, water current, wind flow have been exploited and utilized [16]. The mass level of large flow energy harvester can reach 2 × 10 5 kg, where the energy harvesting magnitude can reach 18.2 KW [17]. Flow energy harvesters can also be minimized as small as a few centimeters and indicate energy harvesting density as 1-10 mW [18,19]. A variety of energy harvesters have been developed based on different energy conversion mechanisms. Among them, the large-scale electromagnetic energy harvester relies on large generators, suffering from complex structures [20]. The approach can produce energy in large magnitudes and can generate electricity feeding the grid for the industrial production process and daily life use. As for triboelectric nanogenerators (TENG) and piezoelectric energy harvesters ...
