This paper proposes a review of several circuits for communication and wireless\nsensing applications implemented on cellulose-based materials. These circuits have been\ndeveloped during the last years exploiting the adhesive copper laminate method. Such a\ntechnique relies on a copper adhesive tape that is shaped by a photo-lithographic process\nand then transferred to the hosting substrate (i.e., paper) by means of a sacrificial layer.\nThe presented circuits span from UHF oscillators to a mixer working at 24 GHz and\nconstitute an almost complete set of building blocks that can be applied to a huge variety\ncommunication apparatuses. Each circuit is validated experimentally showing performance\ncomparable with the state-of-the-art. This paper demonstrates that circuits on cellulose are\ncapable of operating at record frequencies and that ultra- low cost, green i.e., recyclable and\nbiodegradable) materials can be a viable solution to realize high frequency hardware for the\nupcoming Internet of Things (IoT) era.
