Abstract

In the last few years, low power electronic devices have been increased rapidly. The devices are used in a large number to comfort our daily lives. With the rise in the energy usage of these portable electronic devices, there is a need for us to find a way to develop a new harvesting system. Besides that, many issues arise from the use of energy like greenhouse gas emissions, acid rain, climate change, dependency on depleting supplies of fossil fuels especially from politically unstable regions of the world. Today, 80 percent of the world's electricity supply comes from fossil and nuclear fuels, and almost all transport is powered by liquid petroleum (gasoline). The prediction says, energy demand will triple by 2050 and the fossil fuels by definition are non-renewable are destined to run out, as the population grows to 8-9 billion and developing nations elevate living standards. Furthermore, the emissions from the burning of fossil and nuclear fuels create atmospheric, water, and land pollution and toxic waste. To fulfill its needs, one of the effective methods to generate electricity is by using footstep energy generation. The purpose of this research is to generate power from footsteps as a source of renewable energy that can be obtained while walking or standing on certain arrangements such as footpaths, stairs, plate shapes, and these systems can be installed particularly in the more populated areas. In this project the energy of force is generated by human footstep and energy of force is converted into mechanical energy, DC generator will produce the generator. The basic principle behind this system is piezoelectric effect. The piezoelectric material converts the pressure applied to it into electrical energy. Proposal for the work and use of extravagant resources in the footsteps of humans is very much planned for highly populated nations such as China and India. Where the streets, railway stations, and bus stations are overpopulated and packed like sardines that move around the clock. In addition, piezoelectric transduction is more attractive because of its advantages such as simplicity and versatility, thus generating less current than electromagnetic transduction. The idea is to convert the energy of weight into electrical energy. The power that generates to transform kinetic energy into electrical energy.
