Guest Editorial Special Issue on Radio-Frequency Identification (RFID), Sensing, and Imaging

As the demand for low-cost, flexible, and power-efficient broadband wireless electronics increases, materials and integration techniques become critical and face more challenges, especially with the ever-growing interest for “cognitive intelligence” and wireless applications, married with RF identification (RFID) technologies. This demand is further enhanced by the need for inexpensive, reliable, and durable wireless RFID-enabled sensor nodes, driven by applications such as logistics, aero identification, anticounterfeiting, supply-chain monitoring, space, healthcare, and pharmaceutical, and is regarded as one of the most disruptive technologies to realize truly ubiquitous ad hoc networks.
