Magnetic Structured Triboelectric Nanogenerators for Energy Harvesting

Abstract

Abstract. Triboelectric nanogenerators (TENG) have made significant progress as a sustainable energy harvesting technique due to their ease of assembly, high power density, good stability and cost-efficiency. This study develops the magnetic structured triboelectric nanogenerators (MS-TENG) for energy harvesting with different loading frequency. The MS-TENG use magnetic force in the sliding mode to provide the repulsive force. The dielectric and electrode components, in particular, are appropriately connected to the circuit, which is attached to the digital oscilloscope for voltage performance. The copper capsules in mode two were the most effective design for the MS-TENG. The highest load-circuit voltage of 4.0 V is obtained for the copper (Cu) MS-TENG in mode 2 (dielectric capsule designed in mode 2 is first coated with a layer of Cu or Al and then covered with Kapton). A peak power in this design is 3.4 µW. The suggested MS-TENG offers a practical way to gather electrical energy via the triboelectric effect, which are suitable for multifunctional applications.
