Ambient Electromagnetic Energy Harvesting Circuit using Rectennas Manufactured with Stereolithography Resin

The paper discusses exploratory results to validate main performances of an ambient electromagnetic field energy harvester implemented on a limited surface of non-dedicated polymer object fabricated using 3D Molded Interconnect Devices (3D MID) technology or Plastronics. The prototype is experimented with discrete devices (−7.5 dBm minimum total input RF power, 14.75% global efficiency).
