Efficient Energy Harvester for Microbial Fuel Cells using DC/DC Converters Abstract— Microbial fuel cell (MFC) is an emerging technology for sustainable energy production. An MFC employs indigenous microorganisms as biocatalysts and can theoretically convert any biodegradable substrate into electricity‚ making the technology a viable solution for sustainable waste treatment or autonomous power supply. However‚ the electric energy currently generated from MFCs is not directly usable due to the low

same. A paper battery is a flexible‚ ultra-thin energy storage and production device formed by combining carbon nanotubes with a conventional sheet of cellulose-based paper. A paper battery can function both as a high-energy battery and super capacitor ‚ combining two discrete components that are separate in traditional electronics . This combination allows the battery to provide both long-term steady power production as well as bursts of energy. Being Biodegradable‚ Light-weight and Non-toxic

chapter 1 [pic] 1.1 Objectives of the Study Prepaid energy meter are being used worldwide to improve the collection of funds for the energy used. Weather it is developed nation or developing nation all electricity boards are facing two major issues 1. Power Theft 2. Collection of funds In the existing system the above two problems are non predictable and time consuming process respectively. To overcome these things in the proposed system Cal cards has developed and implemented
