全无源UHF RFID标签的设计保持成本效益，但提供增强的功能，代表了一个雄心勃勃的和刺激的挑战，因为这样的设备将铺平道路的一大类应用，其中识别，计算，自动认知和无线传感是必需的。在这项工作中，提出了两个解决方案。前者名为RAMSES，针对基于RFID的传感进行了优化，并依赖于利用新一代I2C-UHF RFID芯片的新方法。RAMSES能够将传感器数据写入EPC，并与传统的UHF RFID Class-1 Generation-2（Gen 2）读取器进行长达5米的通信。后一种解决方案名为SPARTACUS，放弃了部分长操作范围，以换取额外的计算能力，从而增强与RFID读取器的交互。SPARTACUS代表了RFID设备嵌入传感/驱动功能，分布式计算和与阅读器完全双向通信的文献中的第一个例子。令人满意的工作范围，传感，计算，数据存储和成本效益的主要优势，使所提出的设备绝对适合广泛的新颖和非传统的RFID应用。
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.
