Harvesting the mechanical energy of ocean motion are finding different applications for offshore exploration and ocean monitoring. Because of the very low and varying frequency, from 0.1Hz to 2Hz, harvesting this energy has an important hurdle. In this paper, we provide a comprehensive study of a new idea to supply low power oceanic drifters using an electromagnetic vibration harvester. Therefore, this work presents a solution on how to generate power from low frequency driven electromagnetic energy harvester for an ocean drifter self-powered system. A prototype with a proposed electronic harvesting system is built and tested in a real medium, showing the results before concluding the article
