Abstract: Rolling-spherical triboelectric nanogenerator (R-TENG) are increasingly favored by wave energy researchers
because of their excellent work performance for low frequency, highly random wave energy. To realize the quantitative
research on the performance of R-TENG under specific wave conditions, this paper proposed a high-fidelity and multi-
physics coupling modeling method for R-TENG based on COMSOL Multiphysics simulation software. By using the
model, the multi-physics coupling effect and power output of R-TENG under specific wave conditions can be accurately
and efficiently simulated. This model can be regarded as the development and improvement of static simulation methods
based on electrostatic field commonly used at home and abroad. Based on this method, this model investigated the
modeling and performance of a four-electrode R-TENG, and provided the high-precision, real-time and quantitative
simulation of the whole process from the wave-making to the power output. This made it possible to carry out the
structural optimization design and finally to provide effective means to manufacture.
Key words: wave energy; rolling-spherical triboelectric nanogenerator; COMSOL; simulation of high-fidelity; coupling
