Metal-oxide thin-film transistor technologies find today their application in display products acting as active component in backplanes to drive LCD or OLED frontplanes. These transistors implemented in a thin-film transistor circuit are also ideally suited for next generation connected products that embed such low-cost, flexible, ultrathin circuits in everyday items. Item-level Internet-of-Things applications are therefore the main driving force for the research on metal-oxide RFID circuits. In this lecture, we will discuss the current state-of-the-art of thin-film RFID tags, including the first product prototype together with our partner company Cartamundi. In addition, we will discuss the roadmap to upscaled manufacturing and the next generation thin-film circuit activities.
