Energy harvesting from transverse ocean waves by a piezoelectric plate

摘要: Abstract An ocean wave energy harvester from the transverse motion of water particles is developed by piezoelectric effects. The made two horizontal cantilever plates attached patches and fixed on a vertical rectangular column. To describe harvesting process, mathematical model to calculate output charge voltage according Airy linear theory elastic beam model. influences root mean square (RMS) generated power patches, such as depth, location under surface, length cantilevers, height, ratio are discussed. Results show that RMS increases with increase in cantilevers decrease distance surface depth. As result, an optimum depth obtained achieve maximum at different locations surface. A value up 30 W can be realized for practical values length, height 10.6 m, 21.2 m, 4 m, −2 m, respectively. This research develops novel technique leading efficient waves harvesters could easily offshore platform.
