“…Then, four pieces of Al foils (15 μm in thickness) were selected as one electrode for TENG component and attached onto the four arms of the acrylic framework in a clockwise order. After that, a spring steel sheet with a width of 2.5 cm was chosen as the other electrode material as well as a substrate for FEP film (with glue on the backside and 30 μm in thickness), and the lengths of spring steel sheet and FEP film were adjusted (6,8,10,12, and 14 cm) to realize the device structural optimization. After assembling, the FEP/spring steel sheet was mounted face to face with the Al electrode when keeping the FEP layer in the inner side.…”

“…With the rapid development of the Internet of things, powering the ubiquitous and distributed sensors has become a key challenge [1][2][3][4], and converting ambient energy into available electricity is an attractive approach to solve this problem [5][6][7][8]. Among various types of energy resources in nature, such as solar, mechanical, tidal energies, and so on, wind energy is one of the most attractive candidates because it is a sustainable clean energy with the advantages of wide distribution and enormous reserves [9][10][11][12].…”

“…To date, some wind energy harvesting TENGs with rotational structures [27][28][29][30] and flutter-driven structures were developed [31][32][33][34][35][36], and quite high outputs could be achieved under relatively high wind speeds which were usually higher than 5 m s −1 . However, the global average wind speed near the surface (the observation altitude is 10 meters) is reported to be 3.28 m s −1 [6,37]. Therefore, this factor severely limits the widespread applications of the previously reported TENG-based wind energy harvesters in practice.…”

Global warming and climate change have become one of the most crucial environmental issues due to the rampant consumption of fossil fuels. Emission of nitrogen oxide and sulphur dioxide from vehicles and fossil fuel combustion causes the acid rain, which is hazardous to plants, aquatic animals and infrastructure. To solve these problems, numerous efforts have been devoted towards alternating renewable and low-carbon emission energy source. Ambient hydropower, such as rain drops, river flows, ocean tides contains a tremendous reserve of renewable and clean mechanical energy, which provide a sustainable and continuous energy supply regardless of day or night, season, weather and climate. Therefore, developing the techniques for harvesting the energy of rain drop meets urgent demand for relieving our reliance on limited fossil energy [1, 2]. By transforming the mechanical energy of rain drops into electric signals, a variety of self-powered sensors can be built up, including remote control network, wireless sensor array [3, 4]. Up to now, there are mainly two conversion mechanisms for scavenging the water motion, i.e. electromagnetic [5-8], and piezoelectric effect [9, 10]. As for the electromagnetic harvester, the permanent magnet not only significantly boosts the weight and price but also limits diversity in harvesting water motions. On the other hand, most studies in piezoelectric generator focus on using piezoelectric beams and bands subjected [11-13]. Piezoelectric generators only harvest energy which is affected by impact conditions and surface interactions, so it cannot detect chemical composition. For example, the 'splash' phenomenon may lead to a reduction in energy transfer. The poor output power density and complex fabrication process in piezoelectric generator dramatically hinder their further commercialization. Therefore, a scalable, flexible, lightweight method that efficiently harvests energy from various water movements is necessary. Starting from 2012, by innovatively coupling contact electrification with electrostatic induction, researchers have invented triboelectric nanogenerators (TENGs) to obtain various environmental mechanical energies, such as body motion [14-17], vibration [18-21], rotation [22-25], acoustic wave [26], air flow and water flow[27-31]. With respect to sensing application, arising from the conversion from mechanical motions into output electric signal, TENGs have been extensively exploited to This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…The advance in industrial technology has gradually increased our dependence on fossil fuels, eventually leading to a global energy crisis. [1][2][3][4][5][6] Thus, it is the first priority for scientists to find renewable and clean energy to replace the traditional energy sources that have been dropping at an alarming rate. [7][8][9][10][11][12][13] In 2006, Wang's group first proposed the concept of a self-powered sensor based on a nanogenerator, [14] which could effectively harvest various kinds of mechanical energy, providing a new way for scientists to ease the energy shortage.…”

A reliable mechanical fixation plays a pivotal role in guaranteeing normal operation for large‐scale equipment. The detection of screw loosening or breakage as well as susceptor tilting is of significance in mechanical dynamics, especially in those with large vibration amplitude during operation. Herein, a novel triboelectric nanogenerator (TENG) is reported that consists of polytetrafluoroethylene (PTFE) pellets and a single electrode installed on the bottom of a cylinder. The basic electricity‐generating principle is the coupling of triboelectrification and electrostatic induction between the pellets and electrode. The dependence of the output voltage on the diameter/number of pellets is explored deeply, suggesting, by enlarging the diameter or increasing the number of pellets, the output voltage can be improved. By integrating the fabricated TENG on a vibration table, the capacity of self‐powered detection of screw loosening or breakage can be achieved based on TENGs, which can predict a potential mechanical failure in real time. More importantly, the TENG can be tuned to output eight‐channel data simultaneously, which enables recognizing the tiny inclining signs of equipment. This work provides a new method for the design and manufacture of intelligent sensors that can be used for failure inspection and diagnosis in future intelligent mechanics.
