Study on Wave Power Generator Using Flexible Piezoelectric Device

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 the existing coastal and ocean structures (i.e. breakwater, submerged obstacle, reef in shallow water and submerged plate in deep water) are utilized as a wave power generator attached with the FPED to make a safety and disaster prevention. We examined the usefulness and electric performance of the FPED excited by waves in experiments.
