“…To analyze the vertical mode, we derive the relationship between voltage and charge based on the Gauss theorem and the distribution of charges. This relationship, known as the V-Q-x association [42][43][44][45][46][47], is entirely electrodynamic. By understanding this relationship, we can better understand the TENG's performance in the vertical (contact-separation) mode and design more efficient TENGs in the future.…”

Developing cost-effective and efficient energy harvesting technologies is critical with the rising demand for clean and sustainable energy. In this research paper we presents a CFD-based study on a PDMS-Graphene Triboelectric Nanogenerator (PG-TENG) for blue energy harvesting. Our study focuses on the vertical (contact-separation) mode of the PG-TENG and investigates the effect of TENG’s varying size on its electrical output performance. To optimize the properties and performance of the PG-TENG system, we used COMSOL Multiphysics for mathematical-modeling and simulations. The outcomes show that the varying size of the PG-TENG significantly impacts its electrical output capabilities, with larger PG-TENGs exhibiting higher current and voltage outputs. Moreover, we compared our outcomes to other studies on graphene-based TENGs and highlighted the advantages of our PG-TENG in terms of durability, performance, and mechanical stability. Our research contributes to the field of blue energy generation by providing insights into the design and optimization of PG-TENGs for low-cost, effective, and efficient energy harvester devices.

“…A new mode of operation called the diagonal mode which is considered a hybrid mode between both contact and sliding modes has been proposed before. 16 The diagonal mode offers a new degree of freedom and can be used in various applications; however, no analytical model has been developed for it, only the curve-fitting equations have been used.…”

In the past few years, electrical energy harvesting from the ambient environment has attracted much of the research interests due to the increasing need for energy resources that suit the rapid development of power electronic devices. Recently, a novel mechanical energy harvesting and transduction technology has been introduced called the triboelectric nanogenerators (TENGs), with many advantages over the other harvesters. In this work, a new diagonal motion mode for TENGs is studied intensively in the attached electrode regime and simulated using COMSOL MULTIPHYSICS. The diagonal motion mode offers a new way of motion represented in the angle theta ( )-between the left endpoint of the bottom dielectric and the left endpoint of the top dielectric-that ranges from 0 to 90 degrees, and allows for further energy optimization. A complete analytical model of the proposed TENG structure has been derived step by step, and its results were compared to COMSOL simulation results to validate its accuracy. The maximum error between the results is equal to 5.3%, 4.3% and 0.88% for the open circuit voltage (V OC ), short circuit charge (Q SC ) and Capacitance (C) respectively. Based on the developed model, a performance optimization study has been performed on the dielectric material used in the device. The study revealed that, the tribo-pair of Nylon and Kapton corresponds to the best performance of the harvester amongst the other pairs used in the literature with a maximum energy of 0.40118 nJ. In addition to this, the accuracy of the analytical model was a motivation for constructing a Verilog-A model, by which the device was studied under different loading conditions such as simple resistive and capacitive loads. Finally, a MATLAB based CAD tool has been developed to allow rapid prototyping and testing of different device parameters on the device performance.

“…TENGs have the upper hand on the piezoelectric energy harvesters due to the high output power, high efficiency, low cost and the feasible fabrication techniques. 7 As a result, TENGs have proved their competence from the power, efficiency and cost perspectives. 3 They are integrated in wearable technology, 8 biomedical applications and even in self-powered wireless sensors.…”

Summary Energy is a global demand nowadays. Researchers and Scientists are trying every day to find new resources to generate energy. Mechanical energy is considered one of the most essential energy resources in the world. It can be easily generated and transferred into electrical energy. There are a lot of new technologies that are working to develop small and portable energy harvesters for electronic devices such as piezoelectric and triboelectric nanogenerators (TENGs). However, TENGs are more favorable to piezoelectric nanogenerators due to the availability of nontoxic materials. Moreover, they are cheap and exhibit high performance. This article investigates one of the TENG devices, Zigzag structure. It presents an analytical derivation for the model that addresses all aspects of the TENG such as the output voltage, the output current, the capacitance, the resistive load, the capacitive load and the harvested power step by step. The analytical derivation is also verified using COMSOL simulations to validate the results. The mismatch between the analytical derivation and COMSOL is 0.022% in the open circuit voltage and 0.33% in short circuit charge. Electrical behavior is presented afterwards using Verilog‐A in Cadence to examine the performance of the TENG devices in real life situations. For the chosen parameters, the device delivers a maximum voltage of 23 KV at nearly 90° and a maximum current of 7.5 μA at nearly 10°. The maximum reported output power for a load of 5 GΩ is 5.2 mW.
