Abstract

This research presents a low-cost solution towards passive identification and sensing of temperature for multi-applications being vital enablers to sense/measure remote parameters in pervasive artificial intelligent networks. The paper provides a glimpse of temperature sensitive tags with varying parameters/dimensions, number of bits and layout. Two different techniques are encountered for temperature sensing outcomes, later their behavior towards varying temperature is analyzed/captured. In the first technique, a stanyl Polyamide is used as temperature sensitive material; filled in between unique identifier bit slots in chipless RFID (CRFID) tag. Whereas temperature dependent substrate is used in the second technique for three different bit combination tags. The dielectric properties of such materials are varied linearly with alteration of environmental temperature. Moreover, a single bit is dedicated for sensing, whereas other bits are encapsulated for unique ID. Multi bit tag yielding 2-bits, 4-bits and 10-bits response are analyzed and monitored for tagging as well as temperature sensing. Proposed CRFID sensor tags are simulated using CST microwave studio integrated via finite integral technique (FIT). Also, verified via finite element methods (FEM) using HFSS (high frequency structure simulator). Whereas graphical/mathematical verification/modelling is acquired via MATLAB and ORIGIN software. Sensor tag can be deployed for solo dedicated applications as well as multi-parametric analysis. Ultimately, robust, printable, low-cost flexible tags are suitable for irregular surfaces for temperature sensing and tracking of goods for long-term RF sensing applications.
