Abstract
Herein, the rotary triboelectric nanogenerator (R-TENG) with a modified structure is simulated and fabricated to investigate the effect of changes on the geometric structure experimentally. The R-TENGs were fabricated using cost-effective and easily accessible dry-film lithography based on the PCB approach. This process which is explained step-by-step in detail in this paper, provides uniform electrode layers without using high-tech instruments, resulting in enhanced fabrication speed and electrical performance. R-TENGs with varying electrode and PTFE sector counts (32/16, 16/8, and 8/4) were fabricated and analyzed. At 1000 rpm, the output power of R-TENGs with 8, 16, and 32 electrodes demonstrated escalating output power with increasing electrode numbers: 6.82, 19.52, and 30.64 Wm-2, respectively. Simulation results corroborated the experimental findings, confirming that more electrodes and freestanding sectors yield superior power density and electrical generation. The 32-electrode, 16-sector R-TENG outperformed its counterparts, suggesting that strategic design alterations can significantly optimize energy harvesting in R-TENGs.
期刊介绍:
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
