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.

“…Piezoelectric Sensors : Piezoelectricity is a term used to explain materials with anisotropic structures that generate an electrical potential in response to applied mechanical stimuli due to the electric dipole moments. As is well‐known, dynamic measurement needs a sensor to achieve transient sensing capabilities and high sensitivity with the typical frequency range between 10 Hz and 50 kHz . Therefore, piezoelectric sensors with the impressive characteristics of self‐power ability and low power consumption have a superiority to detect the high frequency of pressure.…”

Wearable/flexible electronic sensing systems are considered to be one of the key technologies in the next generation of smart personal electronics. To realize personal portable devices with mobile electronics application, i.e., wearable electronic sensors that can work sustainably and continuously without an external power supply are highly desired. The recent progress and advantages of wearable self-powered electronic sensing systems for mobile or personal attachable health monitoring applications are presented. An overview of various types of wearable electronic sensors, including flexible tactile sensors, wearable image sensor array, biological and chemical sensor, temperature sensors, and multifunctional integrated sensing systems is provided. Self-powered sensing systems with integrated energy units are then discussed, separated as energy harvesting self-powered sensing systems, energy storage integrated sensing systems, and all-in-on integrated sensing systems. Finally, the future perspectives of self-powered sensing systems for wearable electronics are discussed.

“…BaTiO 3 , TiO 2, graphite, graphene, ZnSnO 3 nanocubes, polytetrafluoroethylene, and many other solid materials had been applied as doping materials to PDMS, which remarkably promoted the output performance and the development of TENG. [ 13,26–30 ] However, liquid doping materials were neglected in past TENG materials study, even the kinds of liquid are abundant as solid's. The variety of liquid would extend the choice in TENG materials which would benefit the development of TENG.…”

Material functionalization of triboelectric nanogenerators (TENG) plays an important role in TENG's electric performance for sustainable energy harvesting. In this work, a method for improving polydimethylsiloxane (PDMS) composites triboelectric performance has been proposed, via filling high dielectric constant liquid (instead of solids) into PDMS matrix. The improvement is attributed to the high dielectric constant liquid in PDMS matrix that reduced the effective thickness of PDMS and increased the dielectric constant of PDMS composite synchronously. At 50% filling ratio (PDMS‐HD50), the triboelectric performance exhibits an enhancement of 4.5‐fold in output voltage and 3.9‐fold in output current as compared to pure PDMS. The results, besides higher transparency, are superior to the results from traditional solid dielectric constant doping materials like BaTiO3 nanoparticle in PDMS. This work has proved potentials of dielectric liquid filling materials in fabricating TENGs and could be a guidance for exploring new liquid filling materials.
