Two-dimensional materials are the thinnest materials every created by human beings. They are thin as few atoms, and they have shown unpreceeded electrical, optical and mechanical properties, never observed at the same time in any other materials. Being ultimately thin, they represent the best choice for flexible, portable and wearable applications, opening the path towards the realization of complex electronic systems, which can be applied in several applications such as Internet of Things (IoT), biomedical and anticounterfeating applications just to cite few.
One of their added values is that they can also be printed as a normal ink, through contactless and low-temperature inkjet printing technology, which is compatible with delicate substrate as paper. Fabricating device on paper is one of the target that Industry is seeking, while exploiting the cheapest, biodegradable and biocompatible substrate available, and which could represent the solution for the reduction of electronic waste affecting nowadays our enviroment (i.e., green electronics).
