Abstract
The use of energy harvesting technologies for supplying power generating energy to wireless devices and sensors, particularly in scenarios where it is difficult to exchange or recharge batteries, has recently attracted considerable research attention. In this context, we report the design of a piezoelectric energy harvesting system that can be used to harvest energy from the ocean. The harvester is composed of a piezoelectric cantilever structure and a magnet as the tip-mass of the piezoelectric module, atop which a rail (tube) with a metal ball is positioned. The system is tested with a setup that simulates ocean waves. Our findings indicate that our approach can be utilized in the design of multipurpose piezoelectric energy harvesting systems for low frequency vibration and in "sea-based" applications involving buoys and boats.
