| Research Abstract |
We have developed a way of harvesting electrical energy from ocean power using a Flexible Piezoelectric Device (FPED) consisting of PVDF and elastic material such as rubber, silicon and resin. The proposed FPED has a multi-layered structure with a distance between PVDFs. The electric power can be generated when the electric polarization occurs in the PVDF.
Using the developed FPED, we have proposed and developed a new type of ocean power generator, Elastic Floating unit with Hanging Structures, EFHAS consisting of floating unit and hanging unit as shown in Fig.2 and Fig.3. The EFHAS has two main parts, that is, floating unit and hanging unit. The floating unit can generate electric power from wave power and breaking. The hanging unit can generate electric power from not only wave but also current and vortex. We have investigated a structure of the EFHAS and also examined characteristics of motion and electric performance of the EFHAS in the experiment and ocean field.
