Holst Centre, in collaboration with imec, the Delft University of Technology and the Eindhoven University of Technology, has designed and fabricated a self-calibrating RF energy harvester. The device is capable of harvesting RF energy at lower input power levels than state-of-the-art solutions. When used in combination with a dedicated or even ambient RF source, the new RF energy harvester has the potential to power small sensor systems. The harvester shows excellent wireless range performanc...
