Foot Step Power Generation Using Piezoelectric Material

Power generation and its use is one of the issues. Now-a-days numbers of power sources are present non-renewable & renewable, but still we can’t overcome our power needs. Among these human population is one of the resources. In this project we are doing generation of power by walking or running. Power can be generated by walking on the stairs. The generated power will be stored and then we can use it for domestic purpose. This system can be installed at homes, schools, colleges, where the people move around the clock. When people walk on the steps or that of platform, power is generated by using weight of person. The control mechanism carries piezoelectric sensor, this mechanical energy applied on the crystal into electrical energy. When there is some vibrations, stress or straining force exert by foot on flat platform. It can be used for charging devices e.g. laptop, mobile, etc. The generated power is first applied to booster and output from piezoelectric is increased and given to the battery through unidirectional current controller and ac ripple neutralizer. Output from battery is used for various applications using inverter to convert DC into AC. In this paper we are discussing about applications and generations of electricity in the area of power harvesting.
