design of a frequency up-converted electromagnetic human footsteps energy harvester with dual halbach array

The energy crisis has put the life of humanity at risk over time. thus, the research community has started to use a variety of sources to generate electricity. energy harvested from human weight is one of the promising sources that has a high potential for harvesting energy. the present study presents an electromagnetic energy harvesting system based on human steps. this system employs a plucking-based frequency up-conversion technique and halbach arrangements. a semi-analytical analysis is conducted and evaluated by finite element simulations. the results show a footstep can generate an energy of 1.7 j in a 30×30 cm2 area.
