Fully Self-Powered Electromagnetic Energy Harvesting System

N.Anil Kumar | S. Kolangiammal

Abstract: This paper describes the use of piezoelectric polymers in order to harvest energy from people walking, together with the electronics needed to increase energy transfer and storage efficiency. An electrostatic generator was also included in order to increase energy harvesting. There have been independent solutions in increasing the harvesting efficiency either on the mechanical harvester or on its power management circuitry. Here, piezo electric transducers are used in the keys of mobile phones and also in keyboards of personal computers. Piezo electric transducers are used to convert the mechanical energy applied in the keys to electrical energy i. e. an equivalent electric voltage. The obtained voltage will be read by the Atmel microcontroller so that it will be utilized properly for an electric load e. g. Bulb. This paper can be used in smart mobile phones and also in personal computers to use the charge or voltage for its operation by itself. Coupling an energy harvesting system to existing battery in these devices may significantly improve their energy sustainability that at present is one of its biggest limitations
