Abstract :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.
