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.

Radio Frequency Identification (RFID) and Wireless Sensor Networks (WSNs) have received an ever-increasing attention in recent years, mainly because they represent two of the most important technologies enabling the Internet of Things vision. Although designed originally with different objectives, WSN and RFID represent two complementary technologies whose integration might increase their functionalities and extend their range of applications. However, important technological issues must still be solved in order to fully exploit the potentialities offered by such integration. In this work, an innovative RFID-WSN integration approach is presented and validated. It relies on the interconnection of a new-generation, long-range, EPCglobal Class-1 Generation-2 Ultra-High-Frequency (UHF) RFID tag with a commercial WSN node via the I2C interface. Experimental results have demonstrated the effectiveness of the proposed approach compared to existing solution in the literature. Interesting application scenarios enabled by the proposed RFID-WSN integration approach are briefly summarized at the end of the paper.

The design of fully-passive UHF RFID tags preserving cost-effectiveness, yet supplying augmented capabilities, represents an ambitious and stimulating challenge, as such devices would pave the way to a large class of applications where identification, computation, automatic cognition, and wireless sensing are required. In this work, two solutions are proposed. The former, named RAMSES, is optimized for RFID-based sensing and relies on a novel approach exploiting a new-generation I2C-UHF RFID chip. RAMSES is able to write sensor data into the EPC and communicate up to 5 m of distance from a conventional UHF RFID Class-1 Generation-2 (Gen2) reader. The latter solution, named SPARTACUS, renounces part of this long operating range in exchange for additional computing capabilities enabling an increased interaction with RFID readers. SPARTACUS represents the first example in literature of RFID device embedding sensing/actuation functionalities, distributed computation, and fully bidirectional communication with the reader. Satisfactory operating range, sensing, computation, data storage, and cost-effectiveness are the main strengths making the proposed devices definitely suitable for a wide array of novel and unconventional RFID applications.
