Harvesting energy from our environment has been considered to be a promising approach to address the worldwide energy crisis. Triboelectric nanogenerators (TENG) have been developed to capture the mechanical energy from our living environment and convert it to the electrical energy. In this work, the performance of a TENG system based on fluorinated ethylene-propylene and double Aluminium foils has been investigated for ambient wind detection system; and by simulating the effect of roughness of electrodes, surface electrical potential of the electrodes has been extracted. The focus of this work has been the electrical outputs enhancement of vertical mode TENG. Based on the results of this work, the surfaces roughness of electrodes plays an important role in the electrical output performance of the TENG. We have simulated three types of uniform patterned arrays (rectangular, triangular, and spherical) to improve the efficiency of the triboelectric nanogenerator. The result of this study showed that the surface roughness can effectively enhance the TENG performance. The maximum output voltage is achieved for rectangular-pattern films as the electric potential was increased from -9100 V on the flat surface to -31130 V on the rough surface.
