Abstract

The proposed work aims at exploring and developing new strategies to extend missionparameters (measured as travel distance and mission duration (MD)) of a new class of unmannedvehicles, named Micro Air Vehicles (MAVs). In this paper, a new analytical model, identifyingall factors, which determine the MAV power consumption, is presented. Starting from the newmodel, the design of a nanoarray energy harvester, based on plasmonics nano-antenna technology isproposed. The preliminary study was based on a 22,066,058 22,066,058 62,800-dipole rectenna arrayproducing an output power level of 84.14 mW, and an energy value of 2572 J under a power densityof 100 mW/cm2 and a resonant frequency of 350 THz as input conditions. The preliminary analyticalresults show a possible recharge of an ultra-fast rechargeable battery on board of a MAV and an MDimprovement of 16.30 min.
