Piezoelectric Energy Harvester using Voltage Doubling Rectifier

Now a days number of power sources is present, non-renewable & renewable, but still we can’t overcome our power needs. Among these human population is one of the resources. In this paper we are utilizing the waste energy of foot power with human locomotion is important for highly populated countries like India. The electrical energy produced when the flooring is engineered with piezoelectric technology, by the pressure is captured by floor sensors and converted to an electrical charge by piezoelectric transducers, then stored and used as a power source. This paper describes the design of energy harvester prototype and the power conditioning circuit. The power delivered in this paper will not contaminate the surroundings and it is also will not rely upon the climate conditions. The output of piezoelectric energy harvester (PEH) is very low. In this paper we use voltage doubling rectifier type series synchronized switch harvesting on inductor(S-SSHI).
