Among the available energy harvesters, triboelectric nanogenerators (TENGs) are the most popular technologies for scavenging mechanical energy from ambient sources and converting them into electrical energy. Out of four working modes of a TENG, contact-separation (CS) mode is mostly used in practical applications. A typical CS mode TENG consists of the following components: two dielectric layers for friction, two electrodes for current conduction and a connected load. There are several factors which can affect the output performance of a TENG. Among different factors, dielectric layer's thickness and its relative constant can significantly influence the electrical output of a TENG. In addition, surface structure of the dielectric layers in a TENG has also a great impact on its electrical output. Therefore, this study considers these three aspects and vary them to observe the changes in electric potential distribution between two dielectric layers. A comparative study has been conducted for analysing four intrinsic electrical output of the TENG, including the open-circuit voltage, short-circuit charge, capacitance, and energy. In case of investigating dielectric thickness, thin dielectric film based TENG shows greater voltage, charge and energy compared to the thick one. During investigation of relative dielectric constant, the best electrical output is obtained from higher dielectric constant-based electronegative film in TENG. Regarding surface structures, patterned film based TENG exhibits enhanced output compared to non-patterned one. This study considers COMSOL Multiphysics software for all modeling and simulations of the TENG. With the help of this software the design, material selection and stationary study of the TENG has been performed. Overall, this work can be an ideal reference to the researchers which can help them to design a high performance based TENG.

在可用的能量收集器中，摩擦纳米发电机 (TENG) 是最流行的技术，用于从环境资源中获取机械能并将其转化为电能。在 TENG 的四种工作模式中，接触分离（CS）模式主要用于实际应用。典型的 CS 模式 TENG 由以下组件组成：两个用于摩擦的介电层、两个用于电流传导的电极和一个连接的负载。有几个因素会影响 TENG 的输出性能。在不同的因素中，介电层的厚度及其相对常数会显着影响 TENG 的电输出。此外，TENG 中介电层的表面结构对其电输出也有很大影响。所以，本研究考虑了这三个方面并对其进行了改变，以观察两个介电层之间的电势分布变化。对 TENG 的四种固有电输出进行了比较研究，包括开路电压、短路电荷、电容和能量。在研究电介质厚度的情况下，与厚的 TENG 相比，基于薄电介质膜的 TENG 显示出更大的电压、电荷和能量。在相对介电常数的研究中，TENG 中基于较高介电常数的负电薄膜获得了最佳的电输出。关于表面结构，与非图案化 TENG 相比，基于图案化薄膜的 TENG 表现出增强的输出。本研究将 COMSOL Multiphysics 软件用于 TENG 的所有建模和仿真。在该软件的帮助下，TENG 的设计、材料选择和静态研究已经完成。总的来说，这项工作可以成为研究人员的理想参考，可以帮助他们设计基于高性能的 TENG。
