Triboelectric nanogenerators are shown a recent development in the energy field in various applications powering sensors to biomedical applications. The research development of tribogenerators is trending in the renewable energy area as it can harness waste mechanical energy due to the friction. Studies have shown various mathematical modeling done on the triboelectric principle based on Gauss electric field principle. Triboelectricity generation due to contact electrification depends on various factors that include the surface charge density, materials, the geometrical features of the tribo pairs, the mode of operation in terms of velocity etc. The significance of nanomaterials in the generation of triboelectricity is a research area where polymers have shown good results. In this study, a detailed computational and numerical simulation is done on selected pairs of triboelectric material combination chosen from the triboelectric series. Computational simulation is performed using Comsol Multiphysics to evaluate the output performance in terms of Voc and Qsc. Numerical simulation is performed using MatLab to evaluate the output performance current, power, voltage with respect to time for selected input parameters. The numerical performance of the device is validated by the experiments. The numerical method adopted will be a useful tool for determining the output characteristics of any triboelectric pairs.

“…At Aristotle University of Thessaloniki (AUTH), research on the triboelectric generation of energy is ongoing. Laboratory tests on asphalt surfaces and the settings of electrical conductors (Figure 3) show that low-intensity electric current may be produced by the effect of a rolling wheel on an asphalt layer (Barkas et al, 2019). The objective of the research is to define and design the assemblage to be installed on a pavement surface in the urban road network with a view of producing energy and charging the neighboring street lighting.…”

The expansion of road networks, taken place during the last decades, was driven by technological progress and economic growth. The most innovative products of this trend—modern motorways and international road corridors—provide an excellent level of service, traffic safety and necessary information to travelers. However, despite this undeniable progress, major impediments and respective challenges to road authorities and operators still remain. The present paper analytically presents the main current challenges in the road engineering field, namely: a) financing new projects, b) alternative energy resources, especially renewable energy, c) serviceability, including maintenance of road infrastructure, traffic congestion and quality of the network, d) climate change hazards due to greenhouse gas emissions increase, e) environmental impacts, f) safety on roads, streets and motorways, and g) economy and cost-effectiveness. In each country and over each network, challenges and concerns may vary, but, in most cases, competent authorities, engaged in road development policies, have to deal with most of these issues. The optimization of the means to achieve the best results seems to be an enduring stake. In the present paper, the origin and the main features of these challenges are outlined as well as their tendency to get amplified or diminished under the actual evolving economic conditions worldwide, where growth alternates with crisis and social hardship. Moreover, responses, meant to provide solutions to the said challenges, are suggested, including research findings of Aristotle University and innovative technological achievements, to drive the transition to a more sustainable future.

“…Research effort has been dedicated to improving the performance of the TENG-enabled devices 20 . Since TENG are typically designed by tribo-materials in simple structures, structural design plays a dominant role in the energy harvesting performance of these nanogenerators 21 , 22 . For example, studies were carried out on the TENG-based prototypes designed in the spring-assisted multi-layered structures 23 , robust swing structures 24 , water balloon structures 25 , whirling-folded structures 26 , 27 , floating oscillator-embedded structures 28 – 30 , etc.…”

Triboelectric nanogenerators have received significant research attention in recent years. Structural design plays a critical role in improving the energy harvesting performance of triboelectric nanogenerators. Here, we develop the magnetic capsulate triboelectric nanogenerators (MC-TENG) for energy harvesting under undesirable mechanical excitations. The capsulate TENG are designed to be driven by an oscillation-triggered magnetic force in a holding frame to generate electrical power due to the principle of the freestanding triboelectrification. Experimental and numerical studies are conducted to investigate the electrical performance of MC-TENG under cyclic loading in three energy harvesting modes. The results indicate that the energy harvesting performance of the MC-TENG is significantly affected by the structure of the capsulate TENG. The copper MC-TENG systems are found to be the most effective design that generates the maximum mode of the voltage range is 4 V in the closed-circuit with the resistance of 10 GΩ. The proposed MC-TENG concept provides an effective method to harvest electrical energy from low-frequency and low-amplitude oscillations such as ocean wave.
