growing requirements of IT, backscattering chipless RFID tags are then designed and optimized with in a compact size for high data bits, flexibility, reliability, and printability. Different Ink materials are used in tag design to observe its behavior. Integrated sensors along with printed electronics enhances its significance. Moisture and temperature sensor tags are designed and realized for harsh environments.
Currently, the growth of RFID technology can be categorized in two dimensions. The one covers the standalone RFID systems and the other is paving the path for ultramodern wireless communication to serve various functions such as sensor, broadcasting, navigation etc. One of the significant area of interest of RFID system is increased data capacity in a smaller footprint, so that large number of RFID tags can be deployed capable of transmit more information. Tag structures of different size and shapes are realized to promote the concept of data dense compact chipless RFID tags.
The aforementioned research is motivated by the fact of need for low-cost passive sensor devices. The emphasize is on unique blend of RFID tags with integrated sensors which reflects the cost-effectiveness with robustness. The sensors propose in the research work are independent of discrete sensing components. The current research presenting novel chipless RFID sensors, for detecting and monitoring environmental changes (humidity sensing and temperature sensing). These sensors are in high demands of modern communication era and can be incorporated in various industrial applications. The consequential novel chipless RFID sensor tags having sensing functionality have potential to be deployed in numerous applications and have considered as best choice to be utilized in IoT applications.
