Making a transistor from cotton

Materials scientists in Italy, France and the United States have used cotton fiber to create two types of circuits and transistors: one is a field effect transistor similar to a CPU transistor, and the other is an electrochemical transistor that can be used for low voltage switching and is suitable for wearable computers. . The paper was published in the journal "Organic Electronics".

We all know that cotton is an insulator. How do scientists turn decay into magic? Originally, cotton was used only as a matrix. In order to make it conductive, scientists covered different materials such as gold nanoparticles and turned it into a conductive polymer. In order to convert cotton into semiconductors, it is also necessary to put another polymer and apply glycol to make it waterproof. The cotton circuit that maintains the flexibility has quite extensive application value, for example the cotton clothing can become the computer, built-in GPS and sensor and so on.
