Triboelectric Nanogenerator With Ocean Wave Energy
Abstract:
This research successfully developed and tested an improved triboelectric nanogenerator (TENG) with water waves at the Naval Postgraduate School (NPS). The copper electrode holder and track to which the PTFE tape was attached were printed at NPS via a 3D printer. Both the original and improved TENGs were successfully tested with a linear reciprocating motor at two different speeds and with three different weight conditions. In addition, the improved TENG was also tested with thinner PTFE tape. It was found that the biggest influence on the alternating current (AC) output voltage for the TENG was the frequency at which it was operated. The improved TENG was then simply modeled to predict a peak AC output voltage based on input TENG frequency. Finally, the improved TENG was attached to the side of an acrylic column with the ability to operate only in the vertical (heave) direction. It was tested in a wave tank with seven different frequencies and we found that the improved TENG was successful in producing AC voltage output from the waves of the wave tank.
