Abstract

Techniques and methods of energy harvesting are developed to recuperate energy coming from the ambiance to be transmitted to electronic systems. Energy should be useful in specific applications, to generate a certain voltage level and make capable of delivering a recommended Power to the load. So, the main challenge for energy harvesting is to obtain a significant amount of power efficiently from the environment. This paper describes an overview of power transfer systems and methods of charging low power sensors in industrial plants using harvested RF signals. It introduces a scheme investigation of the RF harvester consisting of receiver antenna and a rectifier circuit to convert the RF signal to DC voltage. Low power consumption circuits are used to achieve the target of highest conceivable efficiency in order to produce the maximum power transfer.
