Abstract
Temperature is an important parameter in cold chain applications and directly impacts the shelf life of perishable produce. Recently there has been much interest in using low-cost RFID tags for item level temperature threshold sensing in the cold chain. In this paper, we present the electromagnetic characterization of a composite oil made up of a mixture of two common cooking oils - grapeseed and coconut oil. We show how variations in the oil composition directly impacts the temperature at which the oil transitions from a solid to a liquid state. Moreover we show how this oil can be interfaced with a chipless RFID tag to create a low-cost, customizable temperature threshold sensor. We show how this sensor can be reliably used to detect threshold crossings of 4, 8 and 12°C, all of which are temperature ranges of interest in food monitoring. Avenues for future exploration and improvement are also discussed.
