Abstract
This paper presents the design of an optical energy-harvester (EH) to power wireless IoT sensors. For the first time, the simulation results of the complete nanorectenna-electronic system are reported, consisting of an N*M Ag-Ti arrow bowtie nanoantenna - MWCNT-I-M diode array, a low-pass filter, and a DC-DC converter. An output voltage value of 3.3 V and an output current of 10 mA were obtained with a 49498*14286 optical array with an area of about 63, 64 mm2. The proposed optical EH paves the way for the replacement of batteries with solar energy, overcoming the limit of photovoltaic applications in wireless IoT sensors.
