“…They do not undergo irreversible chemical reactions [31], thus they have of the order of millions of charge cycles [32]. Compared to batteries, supercapacitors have less complex charging circuitry [33], though they do need some smart solutions such as voltage threshold turn-on switch [6] due to the "zero energy bootstrap problem" [34] as demonstrated by Prabhakar et al, [35]. This is caused when the system starts from a total lack of energy; the harvester must generate enough energy and must also have a large enough voltage for the system to operate stably.…”

Abstract-Miniaturization of devices with higher computational capacity coupled with advancement in communication technologies is driving the growth of deployment of sensors and actuators in our surroundings. To keep up the pace with this growth, these tiny, battery-powered devices need small-sized and high-energy density batteries for longer operation time, which calls for improvement in battery technologies. An alternative is to harvest energy from the environment. An important aspect of energy harvesting is that the devices go through birth and death cycle with respect to their power unlike battery powered ones. Another important aspect is that context information is also generated while devices harvest energy from their ambiance. In this article we provide a comprehensive study of various types of energy harvesting techniques. We then provide some models used in energy harvesting systems and the design of such systems. We also throw light on the power management and networking aspects of the energy harvesting devices. At the end we discuss the major issues and avenues for further research.
