“…2 Thus, from the material point of view, the electron affinity, surface function groups, as well as work function are important factors affecting the output performance of TENG. A vast number of advanced materials have been explored, including graphene, [106][107][108][109] MXenes, 110,111 hydrogels, 112-115 aerogels, [116][117][118] black phosphorus (BP), 119 etc.…”

The advances in wearable/flexible electronics have triggered tremendous demands for flexible power sources, where flexible nanogenerators, capable of converting mechanical energy into electricity, demonstrate its great potential. Here, recent progress on flexible nanogenerators for mechanical energy harvesting toward self‐powered systems, including flexible piezoelectric and triboelectric nanogenerator, is reviewed. The emphasis is mainly on the basic working principle, the newly developed materials and structural design as well as associated typical applications for energy harvesting, sensing, and self‐powered systems. In addition, the progress of flexible hybrid nanogenerator in terms of its applications is also highlighted. Finally, the challenges and future perspectives toward flexible self‐powered systems are reviewed.

“…The results demonstrate a striking growth upon an output current of 23 µA and a voltage of 100 V, whereas the TENG with a flat friction layer only has 0.5 µA under the same measurement conditions. Furthermore, Zheng et al reported a novel aerogel porous polymer film‐based TENG (A‐NGs), as shown in Figure c . Compared to the similar nonporous polymer film‐based TENG (D‐NG), the A‐NGs, which are composites of spongy polymer films, demonstrate an effective improvement in output performance.…”

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.

“…The obtained cellulose aerogel shows high mechanical properties, good biocompatibility, and can be used as an excellent supporting material in many fields . Besides, there are other organic aerogels reported in the literature, such as chitosan, cyclodextrin, polyurethane, PVA, polypyrrole(PPy), polyvinylpolymethylsiloxane, nanofibrous Kevlar, poly(3,4‐ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS), and so on. The properties of organic aerogels can be easily controlled by adjusting the type of the monomer and the combination of different monomers.…”

Aerogels are unique solid‐state materials composed of interconnected 3D solid networks and a large number of air‐filled pores. They extend the structural characteristics as well as physicochemical properties of nanoscale building blocks to macroscale, and integrate typical characteristics of aerogels, such as high porosity, large surface area, and low density, with specific properties of the various constituents. These features endow aerogels with high sensitivity, high selectivity, and fast response and recovery for sensing materials in sensors such as gas sensors, biosensors and strain and pressure sensors, among others. Considerable research efforts in recent years have been devoted to the development of aerogel‐based sensors and encouraging accomplishments have been achieved. Herein, groundbreaking advances in the preparation, classification, and physicochemical properties of aerogels and their sensing applications are presented. Moreover, the current challenges and some perspectives for the development of high‐performance aerogel‐based sensors are summarized.
