In recent years the growing demand for energy has become an international concern. Importantly, whilst tackling this issue, it is critical to increase renewable energy usage as a countermeasure to global warming. Currently, the most widely utilised and researched renewable energy technologies are wind and photovoltaic power generation. In contrast, there has been limited interest in power generation using ocean based energy, such as waves and tides. The ocean provides an unlimited source of renewable energy and the advantages of exploiting this energy source are self evident. In this study, the wave power generation using flexible piezoelectric devices (FPEDs) have been performed. Changing design parameters such as length and thickness of the FPED, some experiments have been performed using a shaker and water tank, and the power generation characteristics has been obtained. A theoretical model to estimate the performance of FPEDs has been also developed and validated.
