These materials will incorporate multiple parameter-sensing mechanisms with enhanced sensitivity. 3 Multiple Parameter Sensing A decisive goal of low-cost chipless RFID sensors is to tag each and every perishable item for checking expiry dates. ) to indicate spoilage. Therefore, to accurately detect expiry dates, it is desirable to have multiple parameters sensing in a single chipless RFID tag. For example, as milk spoils, it emits carbon monoxide and its pH changes. Monitoring both these parameters will give precise monitoring of the condition of milk.
2 LITERATURE REVIEW Smart Sensing Materials Most smart materials have been investigated for DC or low-frequency applications. There is a major gap in microwave characterization of smart sensing materials, synthesis, and sensitivity analysis. Exploring the high-frequency characteristics of smart materials will provide new avenues in passive RFID sensing. In addition, further development is necessary for multifunctional materials wherein the functionality arises from individual nanoscale components that can impart electrical conductivity or responsiveness to light and other physical parameters.

However, machine-to-machine communication creates a significant burden on the cost budget of a system due to the high cost of each sensor node. Alternatively, chipless RFID tag sensors provide identification data and monitor a number of physical parameters of tagged objects without having an active sensor in the tag circuitry .
