Abstract
Triboelectric nanogenerators (TENG), which convert mechanical energy (such as ocean waves) from the surrounding environment into electrical energy, have been identified as a green energy alternative for addressing the environmental issues resulting from the use of traditional energy resources. In this experimental design, we propose rolling spherical triboelectric nanogenerators (RS-TENG) for collecting energy from low-frequency ocean wave action. Copper and aluminum were used to create a spherical frame which functions as the electrode. In addition, different sizes of spherical dielectric (SD1, SD2, SD3, and SD4) were developed in order to compare the dielectric effect on output performance. This design places several electrodes on each side of the spherical structure such that the dielectric layers are able to move with the slightest oscillation and generate electrical energy. The performance of the RS-TENG was experimentally investigated, with the results indicating that the spherical dielectrics significantly impact energy harvesting performance. On the other hand, the triboelectric materials (i.e., copper and aluminum) play a less important role. The copper RS-TENG with the largest spherical dielectrics is the most efficient structure, with a maximum output of 12.75 V in open-circuit and a peak power of approximately 455 nW.
Highlights
Innovative technologies have been developed to extract mechanical energy from the environment and convert it into electrical energy, including electromagnetic, electrostatic and piezoelectric methods [1,2,3,4,5,6,7,8,9,10,11]
The RS-Triboelectric nanogenerators (TENG) were made with copper (Cu) and aluminum (Al) for the various spherical dielectrics
Using a sonic array configuration can enhance the performance of the RS-TENG through better design and optimization of the structure of RS-TENG, as will be considered in future studies [39]. This design presents a design for rolling spherical triboelectric nanogenerators (RSTENG) to collect low-frequency ocean wave energy
Summary
Innovative technologies have been developed to extract mechanical energy from the environment and convert it into electrical energy, including electromagnetic, electrostatic and piezoelectric methods [1,2,3,4,5,6,7,8,9,10,11]. TENG has a number of advantages over electromagnetic (EMG) generation, including higher power density (up to 3200 W/m2 ), lower weight, increased productivity (up to 70%) and lower production costs [6]. It is a significant advance in the attempt to collect low-frequency ocean energy. One available alternative in ocean applications is to change the functioning structure of the TENG by designing rolling spherical versions without assistance to increase the output voltage of mechanical energy from ocean waves and convert it to electric power. By increasing the oscillation the spherical dielectric was able to rotate more, allowing the output voltage to be further increased
