“…It is well known that the resistance of such stretchable electrodes increases with elongation; however, such deviation does not decrease the triboelectric performance of the TENG due to its ultrahigh impedance. In addition, carbon grease and liquid galinstan were also investigated as stretchable electrodes in other reports …”

Triboelectric phenomena can be observed everywhere; however, they are consistently omitted from applications. Although almost all substances exhibit a triboelectrification effect in daily life, chemists as well as materials scientists have performed extensive investigations in both the aspects of basic science and practical applications to promote the development of triboelectric nanogenerators (TENGs). Here, a detailed survey of materials engineering for high triboelectric performance and multifunctional materials toward specific applications is summarized, including constructing micro/ nanostructures, chemically modifying the frication surface, modulating bulk friction materials, the mechanism for improved performance, and preparing materials for implantable medical devices, bionic skin, and wearable electronic devices. Moreover, an in depth discussion of the current challenges and future efforts for strengthening the performance of TENGs is elaborated in detail, which will better guide new researchers toward a deeper understanding of and explorations about TENGs.urgently needed to alleviate a more severe energy crisis, which has diverted extensive attention toward renewable energy (solar energy, geothermal energy, etc.) by virtue of its large quantity and ubiquitous existence in our environment. [1][2][3][4][5][6][7][8][9] In addition, the rapid development of science and technology has also suggested higher requirements for energy delivery. In the past few decades, large numbers of mobile communication electronics, smart wearable devices, and internet of things (IoT) devices based on tens of thousands of sensors have appeared in every corner of the globe. These electronic devices are usually characterized by requiring a small amount of power, only on the microwatt or even the milliwatt level, whereas they hold a relatively large shape to facilitate frequent charging or battery replacement for embedded traditional solid-state power sources. It is, therefore, desirable to integrate an energy harvester together with a battery to form a self-powered system that could be recharged by absorbing and transferring external fragmental energy. Furthermore, considering that a majority of these electronic devices are closely contacting the human body, the individualization of the energy-supply mode related to the person itself remains to be studied in depth.To tackle energy shortages and content-specific power supply requirements, researchers have designed a diversity of energyconversion devices derived from assorted working principles to collect energy, such as solar cells, electromagnetic generators, thermoelectric generators, piezoelectric nanogenerators, and triboelectric nanogenerators (TENGs). [10][11][12][13][14][15][16][17][18][19][20][21] Primarily benefiting from their light weight, low cost, multiple structures, extensive material selection, and even great efficiency at low operating frequencies, the novel TENGs have been proven as up-and-coming candidates to complementarily solve the energy-deficiency issue.

“…Depending on these intermediate layers, electrostatic harvesters can be considered as electret-free (without intermediate material) [41], electret-based (electret material) [41] and triboelectric (two different materials -triboelectrification-) [43], which is represented in Fig.6. Electrostatic technology is normally applied to harvest environmental vibrations [41] but they can be also used to harness rotational motion [44]- [49] and strain-deformation [50]- [52]. 2) Secondary MEHTs: MEHTs that are based on the previous principles of operation are now analyzed.…”

Traditional industry is experiencing a worldwide evolution with Industry 4.0. Wireless sensor networks (WSNs) have a main role in this evolution as an essential part of data acquisition. The way in which WSNs are powered is one of the main challenges to face if Industry wants to achieve the digital transformation. Energy harvesting technologies are one of the possible solutions to this challenge. The main purpose of this paper is to present a novel method to taxonomize knowledge in the field of mechanical energy harvesting to enhance the use of energy harvesting technologies in industrial applications. The methodology is based on the analysis of key parameters and performance metrics for existing technologies. The taxonomy is applied to rail axles in order to select the energy harvesting technology that is more appropriate for this specific location, demonstrating the potential of mechanical energy harvesting technologies (MEHTs) for the railway industry, as a use case of industrial environment. Additionally, the taxonomy allows to identify upcoming challenges for research purposes while analyzing the compatibility among mechanical energy harvesting technologies in order to create hybrid harvesters.

“…Moreover, conductive fabrics are used in garments with functional sleeves (to type pager messages, dial phone numbers, and play music) and in apparels with integrated communication devices . As the trend of wearable electronics increases, there is a strong need for the development of comfortable, wearable, and stretchable energy harvesters for users . Nonflexible energy providing batteries have limited lifetime, are heavy in weight and uncomfortable, and cause environmental problems during recycling .…”

The preparation of functional fabrics with enhanced electrical properties requires suitable selection of surface modification and particulate systems as fillers. The best choice would be to use materials with low fiber diameters, good shape stability, and comfort-related properties. In this study, a composite nonwoven fabric "Milife" with surface covering by a particulate-based copper layer was investigated. Electromagnetic, electrical, and transport characteristics of the prepared materials were evaluated. The results showed extremely high total electromagnetic shielding effectiveness accompanied by very good air permeability and moderate bending modulus, indicating comfort behavior. The copper-coated Milife exhibited good potential to be used in protective textile clothing where a combination of electromagnetic interference shielding and antimicrobial effect is required.
