“…It is found that the accordant direction of piezoelectric polarized charges and triboelectric induced charges would enhance power outputs, while their opposite direction would tremendously reduce electricity generation. According to the number of electrodes and combination ways of PENG and TENG, there are three different coupling modes of PTHNGs ( Figure a), i.e., mode I in which PENG and TENG share a pair of electrodes, mode II in which PENG and TENG share one common electrode, and mode III in which PENG and TENG work independently . Although each mode has its own characteristics, their electrical generation processes can be roughly divided into three steps, i.e., 1) TENG contacted and PENG pressed, 2) TENG contacted and PENG released, or 3) TENG separated and PENG released, according to the contact or separation state of triboelectric material and the compress or release state of piezoelectric material.…”

fields is breaking out, such as the Internet of Things (IoTs), big data, humanoid robotics, and artificial intelligence (AI). Nowadays, the rapid advancement of these functional electronic devices is transforming the way people communicate with each other and with their surroundings, which has integrated our world into an intelligent information network. Owing to that no electronics works without electricity, the processes of human informatization and intelligence depend on broad energy supplies and powerful power supports. In other words, electric power can be regarded as the flowing blood that keeps every components of the current society running normally and healthily. However, with the rapid consumption of conventional fossil fuels as well as the growing voice of environmental protection, the current energy structure and its supply status are facing unprecedented challenges. On the one hand, the overwhelming energy crisis and ecological deterioration have become huge bottlenecks restricting socioeconomic development.[1] Some serious situations may even worsen to the root of interstate interest conflicts or the disaster that threatens the survival of mankind. In this case, the transform of energy structure from scarce, pollution-prone, and irreproducible mineral resources to abundant, environmentally friendly, and renewable green energies is desperately required. On the other hand, the traditional centralized, immobile, and ordered energy supply patterns based on power plants are incompatible with the present development of functional electronics associated with individual person, which follows a general trend of miniaturization, portability, and low power. As the information age is coming, billions of things must be connected with sensors for various measurements, perceptions, controls, and data transmissions. [2] These mobile, human-oriented, randomly and massively distributed sensing networks also require the corresponding matched power supply system. Therefore, it turns out that the unreasonable energy structures as well as the mismatched supply pattern lead to the current development dilemma.Portable power supplies and self-powered systems are the most promising solutions for the above straits. For wearable power sources, one of the compromises is to choose small-size Integration of advanced nanogenerator technology with conventional textile processes fosters the emergence of textile-based nanogenerators (NGs), which will inevitably promote the rapid development and widespread applications of next-generation wearable electronics and multifaceted artificial intelligence systems. NGs endow smart textiles with mechanical energy harvesting and multifunctional self-powered sensing capabilities, while textiles provide a versatile flexible design carrier and extensive wearable application platform for their development. However, due to the lack of an effective interactive platform and communication channel between researchers specializing in NGs and those good at textiles, it is rather difficult to achieve fiber...

“…When the PDMS and Ppy come into contact and then separate, electrons transfer from Ppy to PDMS at the interface. As the humidity gradually increases, the surface of the Ppy will adsorb water molecules, leading to weak triboelectric effect and a reduction in the charge transfer [53][54][55]. As shown in Fig.…”

A new self-powered active gas sensor for realtime monitoring of automotive exhaust gas was devised. The pipe-shaped device was fabricated from polydimethylsiloxane/ polypyrrole (PDMS/Ppy) triboelectric gas-sensing unit arrays. The gas-sensing units can actively convert the mechanical energy of gas flow into a triboelectric current. The output current signal depends on the species and concentrations of the target chemical gases (CO, NH 3 , NO) in the gas flow, and thus can be used as a sensing signal. The device consists of seven gas-sensing units with different Ppy derivatives. As the different sensing units respond to the gases in different ways, the device can differentiate between gas species. The working mechanism is attributed to the coupling effect between the triboelectric effect of PDMS/Ppy and the gas-sensing properties of Ppy. The device can be installed in the tailpipe of an automobile, and can thus analyze the exhaust gas in real time without the need for any external electrical power. The results of the present study spur a new research direction for the development of automotive exhaust gas monitoring systems, thus playing an important role in the detection of air pollution.
