Lecturer, Ph.D. Eng. Adrian-Ioan PETRARIU, born in 1984, received the diploma of engineer in Applied Electronics (2009) from the Stefan cel Mare University of Suceava, Faculty of Electrical Engineering and Computer Science. In 2013 he finished the PhD studies at the same university in the field of Computer and Information Technology, the primary activity being the study of RFID systems operating in metallic environments. He attended a 4 month internship of doctoral studies in 2011 at the KaHo Sint-Lieven University in Gent, Belgium, where he studied and tested in detail the effects of metal environments in the proximity of RFID antennas, mostly for HF domain. Teaching activity began in 2012 and in 2016 he holds the position of Lecturer in the Department of Computer, Electronics and Automation at the Stefan cel Mare University of Suceava, with the areas of research interest for RFID systems and impedance matching units, PCB design issues following the SI (signal integrity) and PI (power integrity), LPWAN systems (including LoRa, SigFox, LinkLabs, NB-IoT, etc.) and medical devices for human body signals data acquisition. He worked for various projects within the company Brinton Engineering LLC, of Menlo Park, Canada between March 2014 and June 2015, the primary responsibility being R&D of PCBs and electronic modules for medical devices considering the EMI/EMC standards in the field. Also, during May 2014 to July 2015, he worked for SC Silicon Service SRL, Iași, where he developed various RFID systems used for large volume inventory of metallic objects, being active in the field of HF and UHF RFID antenna simulation, design, and testing. In the period from April 2014 until October 2015, he was a post-doctoral researcher in the project PERFORM - Sustainability performance in doctoral and post-doctoral research, contract POSDRU/159/1.5/S/138963, where the main interest was for long range antenna design in RFID systems used for UHF domain. Recently, his activity is focused on design, simulation, and testing of large-scale, high-density sensor networks in the LPWAN systems and acquisition of medical data. The research activity includes a total of 38 scientific papers (with 20 papers as first author) and 1 patent application with the medical data acquisition topic. From the scientific papers mentioned, 11 papers are published in journals (8 of them indexed in ISI Web of Science) and 21 papers presented at various conferences held in the country or abroad (14 of them being indexed the ISI Web of Science, 1 in Springer and 19 in IEEE Xplore Digital Library). A few scientific papers are with the subject of RFID antenna design and simulations in metallic environments. Recently, all the publications are focused in LPWAN systems and medical signals acquisition devices (a total of 22 papers), one of them being accepted in the first number of 2021 IEEE Internet of Things Journal, a Q1 rank journal with an impact factor of 9.47. Other publications are met in IEEE Access Journal (a Q2 rank journal) and in Sensors MDPI (a Q2 rank journal). Since 2016 he is a member of the PDADMCPI research laboratory from the “Integrated Centre for Research, Development and Innovation for Advanced Materials, Nanotechnology and Distributed Systems manufacturing and control”, which has its location at Stefan cel Mare University of Suceava, where the main activity is R&D of wireless systems, including RFID systems, IoT systems, ZigBee, Bluetooth, Wi-Fi, LoRa and SigFox. Also it was an active member in two projects founded by European Union, PN-III-P2-2.1-BG-2016-0463, “Development and integration of a mobile tele-electrocardiograph within GreenCARDIO© system monitoring and diagnosis of patients”, where his main activity was to develop the hardware component of an wireless ECG, using Bluetooth and GSM/GPRS technologies, and PN-III-P2-2.1-PED-2016-2011, “Visible Light Communications system using adaptive visible light to different environmental conditions”, where was needed to be developed an VLC (Visible Light Communication) system used for some prototype cars, having support from General Electric Company.
