Wave energy system using piezoelectric panel

In this research, we research the characteristics of a new type of wave-power generation system that\ud deducts ocean wave energy to the front part by installing a piezo-electric element on the outside of the existing harbor\ud structure. The wave-power generation system proposed in this research might be applied to a variety of marine structure,\ud which makes it possible to add wave-power generation capacity to the original structural function. Furthermore, it cost\ud relatively less to build multiple generators, which makes its wave-power generation for a bigger launch. Moreover, it\ud might be developed in link with a tourism complex by adopting the wave-power generation system. Accordingly, we\ud analyze the usability of the existing marine structure and characteristics and current research trend in the ocean wave\ud energy retrieval of the wave-power generation system. In addition, in order to review hydrographic characteristics of the\ud proposed system, seen from the result of carrying out 2-D cross-section hydrographic model test, it is confirmed that the\ud maximum wave pressure and voltage increase when in the cases of higher wave and longer period. The result from\ud hydrographic model test indicates that wave-power generation system using piezoelectric element has different\ud generation volume depending upon crushing wave height rather than incidence cycle. It also indicates that the\ud generation volume increase in positive proportion to the size of ocean wave energy
