Created the world's first transistors on paper

A team of researchers from Universidade Nova de Lisboa (New University of Lisbon) has developed a way to use paper as a component of field effect transistors. In short, scientists have managed to place the transistors on plain paper.

During testing, the researchers managed to “make devices on both sides of a sheet of paper,” which allowed the paper to work simultaneously “both as a base and as an insulator.”

The new development is supposed to be a serious step in the field of creating thin screens on paper, electronic tags, as well as in the development of new classes of devices.

Plus, “paper transistors” are also extremely cheap to manufacture.
