Topic : Generation of Electricity by Human Motion Using Piezoelectrics

Authors:Gowtham.S ||

Abstract:In physics, energy is property of objects which is transferred to other objects or converted into different forms. In recent days there is a vast scarcity of energy sources, due to depletion of non –renewable sources of energy. So there is a very high requirement of energy conservation. Also, since there is an urge for energy conservation techniques in recent years, there are many devices which run on non-conventional sources of energy. However, a very unique method of generating electricity is piezoelectricity. Piezoelectricity is the electric charge that accumulates in certain solid materials, in response to applied mechanical stress. . In order to generate electricity, the mechanical pressure is acted upon certain sensors called as piezoelectric sensors. The devices consisting piezoelectric sensors are called as piezoelectric devices. Piezoelectric are materials that generate a voltage when they are subjected to mechanical pressure; conversely, when subjected to an electromagnetic field, they exhibit a change in dimension. . In this concept we propose, generation of electricity by human motion. The idea is to put piezoelectric sensors in the footwear of people so as to produce electricity, during their routine activity of walking, cycling, running, etc. The electricity is produced due to the weight of the person acting on the piezoelectric devices and in turn storing that energy for various other purposes. Also, it is evident from the theory and calculations of piezoelectric devices that it is possible to generate a large amount of electricity in a short period of time. Also, the generated electricity is safe to use and also can be used in the form of batteries to charge small voltage power supply devices. Usage of this footwear for a long period of time will result in generating sufficient amount of electricity for daily needs. Mainly, generation of electricity can be done with routine activity itself, instead of consuming conventional sources of energy..

Keywords: footwear, piezoelectric devices, power generated, weight.
