Optical Plasmonic Nanoantenna-MWCNT diode Energy Harvester for Solar Powered Wireless Sensors
2021
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.
Evaluating Correlations in IoT Sensors for Smart Buildings
2021
International audience; In this paper we introduce a dataset of environmental information obtained via indoor and outdoor sensors deployed in the SMART Infrastructure Facility of the University of Wollongong (Australia). The acquired dataset is also made open-sourced along with this paper. We also propose a novel approach based on an evolutionary algorithm to determine pairs of correlated sensors. We compare our approach with three other standard techniques on the same dataset: on average, the accuracy of the evolutionary method is about 62,92%. We also evaluate the computational time, assessing the suitability of the proposed pipeline for real-time applications.
