This paper proposes and discusses a multiband RF-to-DC converter approach that is simultaneous fed from electromagnetic energy that is available in the ambient, at different frequencies bands, and a dedicated wireless power transmission link. The work uses narrow band matching allowing easy high efficiency conversion on its main power source, which is the WPT link. Its performance is evaluated showing...
The use of chaotic signals as an optimal source for wireless power transmission as well as electromagnetic energy harvesting is proposed. The improved performance of rectifier circuits, in terms of higher RF to DC conversion efficiency, when using chaotic signals in comparison to one-tone signals is demonstrated. A 433MHz chaotic generator and a rectifier circuit are designed and implemented in order...
This paper presents a description of a data-base structure that can be used for electromagnetic energy harvesting information by gather energy footprints and relate them with GPS information. The paper describes the information system architecture that is behind the data-base structure and it is expected that it will become a source of information around the world on energy harvesting. Moreover an...
The main goal of the SWAP project is that of designing, implementing and ultimately testing a new breed of wireless sensor nodes with energy scavenging capabilities. Our design will include novel energy scavenging hardware as well as network protocols and algorithms. In this paper, we summarize the outcomes of the first year of the project as well as the way forward to the further phases. In particular,...
