A printed passive radiofrequency identification (RFID) tag in the ultra-high frequency band for light and temperature monitoring is presented. The whole tag has been manufactured by printing techniques on a flexible substrate. Antenna and interconnects are realized with silver nanoparticles via inkjet printing. A sprayed photodetector performs the light monitoring, whereas temperature measurement comes from an in-built sensor in the silicon RFID chip. One of the advantages of this system is the digital read-out and transmission of the sensors information on the RFID tag that ensures reliability. Furthermore, the use of printing techniques allows large-scale manufacturing and the direct fabrication of the tag on the desired surface. This work proves for the first time the feasibility of the embedment of large-scale organic photodetectors onto inkjet printed RFID tags. Here, we solve the problem of integration of different manufacturing techniques to develop an optimal final sensor system.
本文介绍了一种用于光和温度监测的超高频带印刷无源射频识别（RFID）标签。整个标签通过印刷技术制造在柔性基板上。天线和互连通过喷墨印刷用银纳米颗粒实现。一个喷涂式光电探测器进行光监测，而温度测量来自硅RFID芯片中的内置传感器。该系统的优点之一是在RFID标签上对传感器信息进行数字读出和传输，从而确保可靠性。此外，印刷技术的使用允许大规模制造以及在所需表面上直接制造标签。这项工作首次证明了将大规模有机光电探测器嵌入喷墨印刷RFID标签的可行性。在这里，我们解决了不同制造技术的集成问题，以开发出最佳的最终传感器系统。
