The objective of this research is to propose a novel circuit design that enables wireless energy harvesting, which is a new paradigm that scavenges energy from radio frequency (RF) electromagnetic radiation. Compared to other commonly observed alternative energy sources, such as solar and wind, RF harvesting can provide continuous supply of energy, and is not completely impaired by bad weather conditions and indoor use. However, obtaining a usable yield from this energy source is challenging as the amplitude of the arriving signals is considerably low, and the requirements for operating a commercially available sensor mote are proportionally high. The existing state-of-the-art solutions are effective only over narrow frequency ranges, are limited in efficiency response, and require higher levels of input power for successful operation. Thus, this research aims to further the state of the art through the design and optimization of a novel RF harvesting board design and exploring the interfacing challenges of this board with a number of practical wireless sensors.
