Abstract

The results of the design and development of a new generation of electromagnetic-based energy harvesting systems that can be readily installed in various vehicles are presented. The device resembles a conventional damper or shock absorber that is commonly used for vehicle suspensions. Such devices have received increased attention in the recent years with the much publicized development of GenShock by a group of MIT students. The device described in this study is different than the GenShock technology in that it does not use any fluid, is simpler, and can potentially provide a larger amount of electrical power. The presentation will provide a detailed description of the development of a prototype energy harvester, including the modeling and analysis of the electromagnetic components for increased efficiency. The laboratory test results of the prototype system indicate that more than 20 Watts of RMS energy can be realized at displacements and velocities that resemble the relative motion across a vehicle suspension.
