Amin Behzadmehr University of Sistan and Baluchestan Journal Article 2025 04 21 A vertical two-electrode polymeric nanogenerator energy harvester, utilizing KAPTON and PDMS as the positive and negative triboelectric materials, respectively, was investigated through both experimental and numerical approaches. To simulate environmental low-frequency motions, a vibrational force of 20 mN at 8 Hz was applied to the device using a custom-designed mechanical instrument. Experimental measurements confirmed the nanogenerator's ability to generate an output voltage and current with maximum amplitudes of 4 V and 0.025 μA, respectively. The charge production mechanism of the device was then modeled numerically, both with and without the inclusion of the edge-effect capacitor. The modeling results demonstrated strong agreement with experimental data, with the incorporation of the edge-effect capacitor significantly improving the alignment between calculated and observed values. The validated model provides a valuable tool for designing high-performance triboelectric nanogenerators for various applications and conditions. Additionally, further investigations into environmental influences revealed reduced device performance at lower pressures and higher temperatures. https://chal.usb.ac.ir/article_9205_5083e734701199f88431efbee8a937a6.pdf
