Novel fully-passive multifunction RFID-enabled devices

摘要

The emerging radio frequency identification (RFID) technology is more and more adopted in a huge range of application scenarios. Nevertheless, in many of them, a real added value would be given by the use of novel RFID devices which, while ensuring cost effectiveness and ease of use, also guarantee augmented functionalities, such as on-board sensing and computation. In such a field, this work presents the progress in the design of smart, multi-function, RFID-enabled devices at the Electromagnetic Lab Lecce. Specifically, the preliminary prototypes of SPARTACUS and RAMSES, which are the two UHF RFID tags with augmented functionalities introduced in our earlier works, have been significantly improved in terms of compactness, antenna design, sensing and computing capabilities. The achieved operating ranges and sensing performance are the main strengths making the two devices definitely suitable for a wide array of applications.
