This study presents a comparative analysis focused on simulating the operational modes of a triboelectric nanogenerator (TENG) using simulation-based method. Simulation modeling was performed using a demo version of the Comsol Multiphysics software. The simulations were conducted under both open circuit and short circuit conditions. The study provides the voltages across the surface of the electrodes under open circuit conditions and the transferred electrical charges under short circuit conditions, along with their respective graphs. The study examines the four main operating modes of a TENG—Vertical Contact-Separation Mode, Lateral Sliding Mode, Single-Electrode Mode, and Freestanding Mode—simulated under specific parameter sets. These results hold significant importance in the design stage of a Triboelectric Nanogenerator (TENG), as each working mode necessitates a specific interface circuit to harvest energy efficiently. Therefore, the evaluation of the findings of this study can be instrumental in the design optimization of TENG structures.

Bu çalışma, simülasyon tabanlı yöntem kullanılarak bir triboelektrik nanojeneratörün (TENG) çalışma modlarının simüle edilmesine odaklanan karşılaştırmalı bir analiz sunmaktadır. Simülasyon modellemesi Comsol Multiphysics yazılımının demo versiyonu kullanılarak yapıldı. Simülasyonlar hem açık devre hem de kısa devre koşullarında gerçekleştirilmiştir. Çalışma, açık devre koşulları altında elektrotların yüzeyindeki voltajları ve kısa devre koşulları altında aktarılan elektrik yüklerini ilgili grafikleriyle birlikte sağlar. Çalışma, belirli parametre setleri altında simüle edilen bir TENG'in dört ana çalışma modunu (Dikey Kontak Ayırma Modu, Yanal Kayma Modu, Tek Elektrot Modu ve Bağımsız Mod) inceliyor. Bu sonuçlar, Triboelektrik Nanojeneratörün (TENG) tasarım aşamasında büyük önem taşıyor çünkü her çalışma modu, enerjiyi verimli bir şekilde toplamak için özel bir arayüz devresi gerektiriyor. Bu nedenle, bu çalışmanın bulgularının değerlendirilmesi TENG yapılarının tasarım optimizasyonunda faydalı olabilir.
