Special Issue on Energy Harvesting

Abstract

With advances in low-power electronics, the cost and power requirements of many electronic devices have dropped significantly in recent years, thereby enabling their widespread deployment in, for example, sensor networks or embedded micro-actuated components. In such applications, the limiting factor in their lifespan is often the life of the power source. To overcome this issue, there is a growing interest in scavenging otherwise wasted energy from the ambient environment to provide a limitless source of low-level power for these devices.
