Abstract
This paper presents a novel temperature sensor tag for passive UHF RFID systems and discusses a method to perform measurements in practice. The developed sensor tag is fabricated from cost-efficient and commercially available materials. Distilled water is used as the temperature sensitive material instead of the more traditional semi-conducting materials. The tag is fabricated on a FR-4 substrate which provides a rigid backing for the tag. The sensor can be constructed with a commercial passive UHF RFID IC. The temperature sensor tag's measurement range spans from a theoretical low of 0 up to over 74 °C. The read range of the tag, in free space, is over 7 metres.
本文提出了一种用于无源超高频射频识别系统的新型温度传感器标签，并讨论了在实际中进行测量的方法。开发的传感器标签是由具有成本效益和商业可用的材料制成的。蒸馏水被用作温度敏感材料，而不是更传统的半导体材料。该标签在FR-4基板上制造，该基板为标签提供刚性背衬。该传感器可以用商用无源UHF RFID IC构建。温度传感器标签的测量范围从理论低点0到超过74°C。在自由空间，标签的读取范围超过7米。
