We have developed a new wave power generator using flexible piezoelectric device (FPED) which is a hydro-electric ocean energy unit designed to convert renewable energy harnessed from ocean energy into usable electricity. In our previous works, the FPED consisting of piezo-electric polymer film (PVDF) is a way of harvesting electrical energy from the ocean power, e.g. tide, current, wave, breaking wave and vortex. The concept of this study is that existing coastal and ocean structures (i.e. a breakwater, submerged obstacle, reef in shallow water and submerged plate in deep water) are utilized as a wave power generator sticking with the FPED to make a safety and disaster prevention. We examined the usefulness and electric performance of the FPED deformed by waves in experiments.
