An energy harvester exploiting the pitch oscillation of a sensor buoy is presented and analyzed. It consists of a magnetic cylinder rolling on a track located inside the buoy and adjacent to some coils. A simple model able to predict the harvested power in presence of regular and irregular pitch movements is proposed. An experimental prototype was created with a 3D printer and was tested to extract the main parameters of the harvesting system. These are exploited to optimize the harvester design and to predict the harvested power when connected to a rectifier and a DC/DC converter implementing an MPPT algorithm.

Abstract
An energy harvester exploiting the pitch oscillation of a sensor buoy is presented and analyzed. It consists of a magnetic cylinder rolling on a track located inside the buoy and adjacent to some coils. A simple model able to predict the harvested power in presence of regular and irregular pitch movements is proposed. An experimental prototype was created with a 3D printer and was tested to extract the main parameters of the harvesting system. These are exploited to optimize the harvester design and to predict the harvested power when connected to a rectifier and a DC/DC converter implementing an MPPT algorithm.
