POWER PRODUCING FLOORING USING PIEZOELECTRICITY

Energy harvesting is very fascinating area of research, now when the whole world is looking for green energy as the alternative source. This paper describes the design of energy harvester as a prototype and the power conditioning circuit. The optimization of the extracted power out of the piezoelectric tile has been presented. The generation of electric energy, when some load is applied on the sensor either in the form of direct strains or ambient vibrations depends upon various factors such as numbers of piezoelectric transducers, electromechanical coupling coefficient of the piezoelectric sensors, amount of the load applied, and also on the scheme of arrangement. Energy harvester floor tile has been designed with inferior quality piezoelectric diaphragms which are used in the buzzers. An efficient way has been presented to capture the generated energy by the dedicated IC and boost it by a converter to get regulated output for charging the batteries of smart phones. The complete charge cycle has been studied for the developed of the system. The simulation and experimental studies have been successfully carried out and the model design and testing was purely for studying the energy generation and capturing phenomenon in the efficient manner. It can be implemented to generate large power by suitably considering the several factors as mentioned above and implementing it on the large scale.
