An electromagnetic energy harvester for vibrations generated by the human body is proposed. The proposed energy harvester comprises a magnetic spring and inductive components. It is preferred to use the magnetic spring for human body vibrations, which are aperiodic in a very low frequency domain. The inductive components are composed of planar coil layers. The use of a planar coil reduces the size of the harvester, and the multilayer structure of the planar coil enhances its transduction efficiency. The harvester generated electrical energy in a frequency domain ranging from 1 to 15Hz, and its output power was 430W. When the harvester was applied to the human body, the output power was 500W.
