摘要

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 (θ) - 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.
