In this paper we propose a realistic nano-rectenna able to harvest from human heat in the infrared frequency band (around 30 THz). The full-wave designs of both an array and a multi-element antenna are presented, taking into account the non-trivial behavior of gold at these frequencies. The use of an original diode realized on a graphene layer, and the derivation of its model from ballistic theory,...
In this paper, we investigate several rectenna architectures to exploit THz energy sources in the infrared (IR) region for a twofold purpose in energy-aware RFID applications: on one hand to harvest from solar energy, on the other hand to wirelessly receive power from dedicated infrared sources on an as-needed basis. The crucial role of the radiating portion is deeply discussed. A tunnel metal-oxide-metal...
