RFID systems can be designed to operate in a variety of frequency bands, depending on the transmission distance and data rate required for the application. A tag capable of sensing some characteristic of its environment and relaying that sensor data in addition to its identification information is known as a sensor tag. RFID tags can be active, with an on-board power supply such as a battery or passive, harvesting their energy from the RF signal sent by the reader. Wireless communication takes place between a central transceiver, or reader, and a simple transponder, or tag, which is attached to an object of interest. Radio Frequency Identification (RFID) is a technology that enables wireless short- and medium- range tracking and identification of objects. These tags could be used to form a network of printed, flexible, passive, interactive sensor tags. Finally, we use these antennas to create passive sensor tags and demonstrate over the air communication of sensor data. We characterize two versions of flexible, screen printed folded dipoles and a meandered monopole operating in the 915 MHz band. ![]() We compare fabrication techniques for flexible antennas and demonstrate that screen and stencil printing are both suitable for fabricating antennas these different techniques are most useful at different points in the design cycle. Here we demonstrate compact, flexible sensor tags with read range comparable to that of conventional rigid tags. However, miniaturized antenna designs often have lower performance. An ideal tag can communicate over a long distance and be seamlessly integrated onto everyday objects. RFID sensor tags consist of an antenna, a radio frequency integrated circuit chip (RFIC), and at least one sensor. Sensor data can be wirelessly transmitted from simple, battery-less tags using Radio Frequency Identification (RFID).
