Mohamed Salman Mohamed Haniff: Waves to Watts: Transforming Energy Harvesting

Download (623.36 kB)

Wave energy is a renewable energy source with abundant reserves, which is largely untapped due to challenges in harvesting its low-frequency oscillations and random nature. A novel tubular liquid-solid triboelectric nanogenerator (LS-TENG) is proposed for wave energy harvesting. In this design, the use of liquid increases the contact area and reduces friction, mitigating the wear and tear issues typically associated with solid-solid TENGs. Preliminary experimental analyses were carried out on horizontal shaker using water as the liquid material and Teflon as the solid material. Initial results are promising, indicating a substantial output. The performance of the LS-TENG under tilt motion will be tested, followed by testing in a wave flume and potential deployment in the ocean. LS-TENG demonstrates significant promise for wave energy harvesting and shows potential for broader marine energy applications.
