摘要
为实现物流包装的身份和受潮信息双重检测,设计了一种新型的低成本无芯片RFID湿度传感器,使用电耦合LC谐振器(ELC谐振器)作为湿度传感器监测目标环境相对湿度、U型环谐振器作为无芯片编码结构识别目标身份。通过射频仿真软件HFSS研究谐振器结构参数与谐振频率的关系,获得相应拟合公式,为结构参数设计提供理论依据,并在此基础上设计了8位编码结构;系统研究不同质量分数的聚乙烯醇(PVA)溶液对湿度传感器感湿灵敏度和感湿范围的影响,研制出8位无芯片RFID湿度传感器。根据散射参量提取法获得了U型环谐振器的有效电磁参数,表明其具有超材料属性。所研究的湿度传感器具有感湿灵敏度高、编码容量大、结构简单等优点,有望在智能包装领域得到应用。
In order to realize the dual detections of the identity and dampness information of logistical package, this paper presents a new type of low-cost chipless radio frequency identification(RFID) humidity sensor. The electric-LC resonator(ELC resonator) was used as the humidity sensor to monitor the relative humidity of the target environment and the U-ring resonator was used as the chipless encoding structure to recognize the target identity. The relationship between the structural parameters of the U-ring resonator and the resonant frequency was studied using the HFSS RF simulation software. Corresponding fitting formulas were obtained to provide the theoretical basis for the structural parameter design. On this basis, an 8-bit encoding structure was designed. The effects of the polyvinyl alcohol(PVA) solutions with different mass fractions on the humidity sensing sensitivity and measurement range of the humidity sensor were studied systematically. An 8-bit chipless RFID humidity sensor was developed. The effective electromagnetic parameters of U-ring resonator were obtained with the scattering parameter extraction method, which shows that it has metamaterial property. The chipless RFID humidity sensor studied in this paper has the advantages of high humidity sensing sensitivity, large encoding capacity and simple structure, and it is expected to be applied in the field of smart packaging.
