The Use of Piezoelectric as Energy Harvester in Breakwater

Abstract

Nowadays, in the case of the coastal structures, wave breaking and access to clean energy are two important issues, which can be addressed by combining breakwater and vibration-based energy harvesting systems. In the study, the mechanical energy harvester which is produced from the transvers wave motion of water particles is developed by the piezoelectric motion in the breakwater and resulting electrical energy. To study the application of this system, a theoretical model is presented. This study has the objective to know the wind analysis, wave estimation and potential of power produced by sea waves on Enggano Bengkulu island is an area with large potential of sea wave energy. From the result of the research is the wave height 1.035 m and wavelength 44.902 m is also strongly suggest to produce energy for 7.51 kW into breakwater. The results of this project demonstrated that wind analysis, wave estimation with Weibull method and the design of breakwater with piezoelectric system can be utilized to absorb wave energy. This research develops breakwater construction with piezoelectricity as a result, potential novel renewable energy by offshore infrastructure.
