Mild-to-moderate Vibration Sensible Cost-effective Electricity Generating Floor Tile

Abstract

The current contribution presents the development and implementation of a facile electricity-generating floor tile which is capable of producing electricity from human footsteps in an economical way. The proposed harvester (floor tile) consists of two wooden plates, springs, coils, and Neodymium magnets. The production of electricity can be tuned by changing the coil turns, magnetic field strength and foot pressure. The foot pressure causes the vertical motion of the magnet and changes the magnetic flux and thus current produce. The generated electricity can be stored in the battery after rectifying and can be used for powering miniature devices. The proposed harvester can generate approximately 518.5 mW per footstep under the pressing force of 931 N with a significant low cost (~USD 50). It is expected that the simplicity, improved functionality and economical features of the proposed harvester can be a potential mean for the green energy production and can be utilized efficiently in the field of sustainable development of energy industry and internet of things.
