GRETA approach towards new green material technologies

This paper summarizes the main technologies adopted for the design circuits and systems on cellulose substrate useful for RFID tags. This in agreement with the needing of new ”green” and low-cost technological solutions, required from the project GRETA (GREen TAgs), in order to reduce the impact of the spreading of electronic devices in the environment. After a brief introduction and the description of the these technologies, the mandatory electromagnetic characterization of paper substrates is proposed. Finally the examples of designed and manufactured circuits, tags and systems exploiting cellulose substrates are reported.
