Energy harvester for remote sensors systems

We present a high dynamic range and high efficiency energy harvesting system. The designed circuit is a dual band architecture able to capture the largest amount of EM radiation in the urban environment being tuned both at GSM and WiFi operating frequencies. The system handles, with a high conversion efficiency, an incoming power typically ranging from -20dBm to 20dBm and rectifies it into a DC voltage source. Test measurements of the proposed system have confirmed all expectation making the proposed solution suitable to be used in several commercial urban remote low power sensor networks applications as those for buildings monitoring.
