Power Generation Using Piezoelectric Transducers

The electric power consumption is historically high and perpetual. The overdependence on non-renewable energy sources is rapidly depleting naturally available non-renewable resources. The future is safeguarded if the shift to renewable energy sources for power consumption happens efficiently and rapidly. Renewable source in layman terms is energy source with very high reusability and one which replenishes over time. The future is in sustainable and economically feasible, renewable energy source. The shift to renewable energy source is uncomplicated to ponder upon but very hard to implement in large scale. High upfront payments, lack of advanced storage capabilities and terrestrial limitations are some of the reasons which stop mass renewable energy production. Many smart people and scientists came up with alternative electrical sources like solar power generation, wind turbine energy production which are renewable and have high reusability. One of the renewable power generations the paper suggest is piezoelectric power generation using piezoelectric transducers. A piezoelectric transducer transforms mechanical energy to electrical energy. Piezo transducer can use human locomotive energy to transform mechanical energy to electrical energy. Densely populated and developing country like India with high pedestrian population can utilize this mode of power generation to great benefits. Piezo transducers can be placed in areas with high population density, so that the power generation is more. The energy generated can either be stored in batteries or can be directly used to run the load. In this paper, a module consisting of piezoelectric transducers, full wave rectifier and SEPIC Converter has been proposed. The module has been simulated in MATLAB/Simulink and its results has been discussed. A hardware prototype has also been discussed.
