Modeling of rf energy sensing and harvesting using the giant thermoelectric effect in carbon nanotubes

The paper presents the modeling of rf energy sensing and harvesting using the giant thermoelectric effect encountered in carbon nanotubes and proposes a harvester based on this principle. The rf energy is transformed into dc voltage, conferring to the harvesting device the property of self-powering and thus the portability, which is a prerequisite of ultradense wireless nodes that form advanced wireless sensor networks and, in principle, of any portable wireless device.
