Abstract
- This study exploits conductive nickel/copper nonwoven polyester as a new triboelectric material and proves its effectiveness in improving the electrical characteristics of triboelectric energy harvesters and reducing production costs. The tribo-surface charge density as another influencing factor in the triboelectric nanogenerators (TENGs) output performance has also been addressed via pre-implanting charges into the surface of polytetrafluoroethylene (PTFE) film using a compact, small, and inexpensive boost step-up power module as an innovative tool. The open-circuit voltage and short-circuit current of eight TENGs are examined to assess the effect of the triboelectric materials, surface morphology, and charge-implantation process on the TENG performance. Sandpaper is used as a stamp to induce micro/nanostructures on the PTFE surface, and its surface charge density is improved using the proposed boost step-up power module. The main purpose of this study is not to provide a new structure for the TENG; this study provides a feasible way to reduce fabrication costs and increase the output performance of triboelectric energy harvesters. • Employing a novel, low-cost, and high-performance functional material for TENG. • Introducing a novel and low-cost module for charge pre-implanting into PTFE electrets. • Investigating the effect of the proposed methods on the output performance of TENG.
