Abstract

In this paper, an experimental study of wave power generation using flexible piezoelectric devices (FPEDs) is presented. Two alternate configurations to harvest power from waves are proposed. With the first configuration, the FPEDs are installed horizontally into the wave, namely, are parallel to the sea bed. With the second configuration, the FPEDs are installed vertically, namely, are perpendicular to the sea bed. A theoretical model to estimate the performance of horizontally oriented FPEDs is also presented. In this model, the Morison equation is adopted to evaluate the force created by the waves. Results from the theoretical model show valid agreement with experimental results for horizontally oriented FPEDs, operating in various water depths and wave heights.
