Radiative wireless power transfer for energy autonomous wireless sensors
Content of the lecture:
This talk will present the latest advancements in RF energy harvesting and wireless power transfer for autonomous wireless sensors. The basic components of RF energy harvesting systems (i.e., antennas, rectifiers, and dc-dc converters) will be first described, and the main merits and trade-offs of these components will be analyzed. Some solutions manufactured using unconventional materials and processes, leading to flexible and even recyclable RF energy harvesters, will be shown. Finally, examples of passive wireless transponders relying on RF energy, i.e., backscatter radios and harmonic transponders, will be presented and discussed.
Teacher: Dr. Valentina Palazzi
Valentina Palazzi received the M.S. degree in electrical engineering and the Ph.D. degree in industrial and information engineering from the University of Perugia, Italy, in 2014 and 2018, respectively. During her PhD, she did a research period of three months at the Tyndall National Institute, Cork, Ireland, a research period of one month at the Centre Tecnològic de Telecomunicacions de Catalunya, Barcelona, Spain, and a student internship of five months at the Georgia Institute of Technology, Atlanta, GA, USA. Currently, she is a researcher with the High Frequency Electronics Laboratory at the University of Perugia.
Her current research interests include the design of RF components, wireless sensors, radar front ends, wireless power transfer technologies, additive manufacturing processes, and conformal electronics.
Dr. Palazzi is an elected member of the IEEE Microwave Theory and Technique Society (MTT-S) Administrative Committee. She is the past chair of the IEEE MTT-S Technical Committee- 26 “RFID, Wireless Sensor and IoT”, and Early Career Representative of the URSI Commission D “Electronics and Photonics”.
