This paper presents a nonlinear resonator circuit based on the Duffing equation to enhance the bandwidth of wireless power harvesting and wireless power transfer systems. The Duffing resonator circuit can be implemented with passive components. In this paper, analysis of an electrical Duffing resonator is presented. The detailed discussion of the Duffing resonator’s properties is provided. As a proof...
In this paper, a high sensitivity RF energy harvester is presented with a potential application in powering wireless sensors for monitoring the degradation of civilian infrastructures. The harvester captures the ambient energy transmitted from the AM broadcasting stations and provides dc power to a sensor. The harvester discussed here can operate at input power levels as small as-39 dBm and generate...
