Due to a rapid decrease in fossil fuel resources and ever-growing carbon emissions, clean energy is urgently needed as vital solution. In the past two decades, harvesting from ambient environment has attracted much attention. Flow induced vibration performance of cylinder with fins attached were investigated. Four configurations studied: plain cylinder, windward fins, leeward four fins. These c...
This paper reports the design, fabrication, and testing of a permanent-magnet energy harvester generator for body motion. The described generator was capable to extract up to 117μW of power from walking, employing a non-resonant rotational mechanism. The planar generator proposed is composed of a rotor having multiple NdFeB permanent magnet pole-pairs with an eccentric proof mass. The stator ha...

This paper presents a review of MEMS based piezoelectric energy harvesting for low frequency and low power applications. An introduction to MEMS and its components along with the concept of energy harvesting is presented. The paper also presents a device configuration of cantilever based basic components of MEMS energy harvesters, i.e. unimorph, bimorph. Results of different designs for MEMS en...
Since the requirements in terms of power of the electronic applications range wide, the 11 developed Energy Harvesting (EH) systems limit their availability to the less power demanding 12 applications. However, this paper focuses on increasing the energy levels collected in the EH 13 system so that it can be included in more demanding applications in terms of power. Therefore, an 14 electronic ...
Abstract In this paper, the authors investigate energy harvesting on railway bridges. A tuning process based a statistical analysis of mechanical generated by lumped‐mass model is presented and validated. cantilever‐based harvester configuration applied, optimal design 3D printed harvesters studied. The electromechanical behaviour device represented an analytical for estimation harvested from t...
