This paper is based on the results obtained during a high-apprentice PhD carried out with the University of Bologna and IMA SpA, Bologna, Italy. It focuses on a nonconventional exploitation of a self-resonant near-field link at UHF for data communication, to be combined in a compact inductive wireless power transfer system. At LF, the inductive channel is designed to deliver up to 1.3 kW to a resistive rotary heater. At UHF, sensing capabilities are made possible by exploiting self-resonant structures, such as split-ring resonators, one at each far-end side of the link. This network is used in a passive sensing system, to convert the data of a remote temperature sensor, representing the system variable load. The reflected power variations at the transmitter side, due to the dc load variations, are successfully used to perform the sensor readout.

Abstract
This paper is based on the results obtained during a high-apprentice PhD carried out with the University of Bologna and IMA SpA, Bologna, Italy. It focuses on a nonconventional exploitation of a self-resonant near-field link at UHF for data communication, to be combined in a compact inductive wireless power transfer system. At LF, the inductive channel is designed to deliver up to 1.3 kW to a resistive rotary heater. At UHF, sensing capabilities are made possible by exploiting self-resonant structures, such as split-ring resonators, one at each far-end side of the link. This network is used in a passive sensing system, to convert the data of a remote temperature sensor, representing the system variable load. The reflected power variations at the transmitter side, due to the dc load variations, are successfully used to perform the sensor readout.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
