reduction and oxidation reactions occur at the corresponding electrode/electrolyte interface. As a result, the electrons flow orderly to do work with very high energy conversion efficiency. In the last two decades, a drastic change occurring in the world should be the rapid growth of information technology. The ever growing market of portable electrical apparatus raises the demand of portable and customized batteries as power sources. [1] Although the development of modern batteries like fuel cell and lithium ion (Li-ion) battery is also very fast, [2] monitoring, replacing and recycling trillions of batteries are especially arduous because of the vast distribution and short cycle lifetime. Besides, there are growing challenges from the dependence on limited fossil fuel, the demand of growing population and the concern about environmental degradation etc. So it is especially necessary to develop renewable power sources which are high-efficient, clean and sustainable.Triboelectrification (also named as contact electrification) is a wide effect around us, which usually needs to be prevented as the negative effect in many systems. In 2012, triboelectric nanogenerator (TENG) was invented to use triboelectricity for converting mechanical energy into electricity by Wang research group, which is a revolutionary breakthrough in the technology of energy conversion and utilization. [3] Traditional triboelectric generator can only accumulate static charges generated by triboelectrification, but there is no current unless there is a discharging. [4] However, the novel TENG can drive electrons to produce electricity via coalescing electrostatic induction with contact electrification. In the early period, TENG is mainly developed as micro-scale power source, which is used to supply for small portable electric apparatus. With the fast development of TENG, lots of work has been done to explore new approaches to effectively harvesting different forms of water power, namely macro-scale blue energy. [5] As for the development of nanotechnology, there are generally five steps in research: the fabrication of nanomaterials, the property of nanomaterials, the single nanodevice, an array of nanodevices, and the integration of system. With the new emergence of TENG, research in self-powered systems is fast expanding into many fields. [4,6] The rapid advancement of TENG gradually shifts its focus from the discrete devices to more complex integrated systems, which can perform multiple functions. Such integrated systems are expected to work sustainably Ever since the discovery of triboelectric nanogenerator (TENG) by Wang's group in January 2012, various breakthroughs have been achieved in the fundamental mechanisms of TENG as well as the demonstrated self-powered systems. TENG has shown many advantages in micro-scale energy harvesting for applications in sensors and portable devices. As a self-sufficient power source, TENG can be used in conjunction with electrochemical processes as self-powered electrochemistry without the use of exter...

With the prospect of autonomous driving on roads in near future, it is paramount to make the vehicles safe on any driving and road condition. This is only possible by additional sensors to make up for the driver's cognitive and sensory system. Measuring road condition and tire forces especially in autonomous vehicles are vital in their safety, reliability, and public confidence in automated driving. Real time measurement of road condition and tire forces in buses and trucks can significantly improve the safety of road transportation system, and in miming/construction and off-road vehicles can improve performance, tire life, and reduce operational costs.There are three particular branches of research in the area of tire condition monitoring systems (TCMS) including estimation, sensing, and power harvesting. The main focus of this review article would be on progress in estimation techniques, energy harvesting, and also sensing approaches for TCMS based on piezoelectric, electromagnetic, and triboelectric nanogenerators (TENGs). Indeed, the fusion of these three areas in a singular package leads to designing future intelligent tires. The implementation of intelligent tires is highly advantageous for reduction of disastrous accidents,CO 2 , and noise emissions, and also fuel consumption. Figure 1 depicts an intelligent tire with its basic parts, its crucial applications, and advantages. In Figure 1, NGs, PEGs, and EMGs refer to nanogenerators, piezoelectric nanogenerators, and electromagnetic generators, respectively.Advances in applications of sensor technologies, sensor fusion, and cooperative estimation in intelligent transportation systems facilitate having reliable tire forces. Consequently, developing a flexible estimation structure to operate the available sensor data in production vehicles is a preeminent objective of the car manufacturers. In this direction, reliable estimation of tire forces at a reasonable cost is necessary for proper functioning of active safety systems in current vehicles. Longitudinal, lateral, and vertical tire forces make major contributions to velocity estimation, [3] traction and stability control, [4,5] and obstacle avoidance systems. [6,7] This article provides a comprehensive review on intelligent tire and TCMS. The first part of the article describes tire models, techniques for tire force, and tire-road friction The quest to utilize intelligent tires has prompted substantial multidisciplinary research including vehicle dynamics, control, estimation, energy harvesting, and even nanotechnology. This review article presents the progress in the area of tire condition monitoring systems (TCMS) and intelligent tires using devices fabricated based on piezoelectric, electromagnetic, and triboelectric effects. Three main branches of the research in this area are presented, including estimation techniques, sensing, and energy harvesting approaches. The authors delineate the importance of TCMS for vehicle active safety systems, its importance for transportation safety, and also its remarka...

“…So far, most research on TEHs is limited to experimental studies, especially involving the technology of material surface processing. This has resulted in some self-powered prototype sensors tailored to far-reaching applications including active alcohol breath analysers [4], 3D acceleration sensors [5], dynamic displacement monitoring systems [6], and wind-speed sensors [7]. The triboelectric energy harvester studied in this paper can be modified for use in a number of real applications.…”

A triboelectric energy harvester based on a three-degree-of-freedom vibro-impact oscillator is presented. Both the dynamic model of the oscillator and the theoretical model of the oscillator-based triboelectric energy harvester are established. The dynamic response and its effect on the electrical output are considered for various mass ratios and mass spacings. The study leads to the conclusions that the symmetric mass configurations of the oscillator are more beneficial to energy harvesting than the asymmetric cases. The extent of the initial spacing between the masses influences the dynamics of the system and the electrical output by triggering grazing bifurcation. High-order periodicity is found to accompany a reduction in the electrical power. An increase in mass ratio tends to increase the electrical output, and there may exist an optimal mass ratio at which the electrical output is maximized. Chatter and sticking motion can improve the output performance dramatically, while resonance, as usual, corresponds to large amplitude response, but these large amplitudes are not optimal for triboelectric energy harvesting, and thus the maximal output does not appear around resonance. This is different from other types of vibration-based energy harvesters, such as piezoelectric and magneto-
