A REVIEW ON ENERGY HARVESTING FROM VARIOUS NON-CONVENTIONAL SOURCES

Abstract

At present, scarcity of energy is an imperative problem where traditional energy sources are contracting progressively. So men have been rushing for renewable energy sources and researchers have come up with the idea of energy harvesting from our immediate environment. Sunbeams, wind, heat, mechanical stress, RF waves are readily available in the nature and energy is being extracted from these and put into use. This paper principally portrays different schemes of obtaining energy from ambient nature along with their operating principle, pros and cons, usages and impending possibilities. Apart from the above mentioned sources, energy harvesting from human power and other sources viz. Nano materials, Biological Parasitic, Atomic Particle motion are also taken into consideration in this text. This document explores different aspects of modern technologies like Wireless Sensor Nodes (WSNs), Micro Electro-Mechanical Systems (MEMS) which needs to be supplied limitless energy. Existing batteries are not suitable to provide the required power for the lifetime of these systems. Energy is available everywhere and if this energy is harnessed and channelized properly, this will help to provide limitless power to these device.
