Transistor Made From Cotton Yarn 92

MrSeb writes "Altering the very fabric of technophilic society, a multinational team of material scientists have created electric circuits and transistors out of cotton fibers (abstract). Two kinds of transistor were created: a field-effect transistor (FET), much like the transistors found in your computer's CPU; and an electrochemical transistor, which is similar but capable of switching at lower voltages, and thus better suited for wearable computers. Cotton itself is an insulator, but by using various coatings, the team from Italy, France, and the United States was able to make conductor and semiconductor cotton 'wires' that retained most of their flexibility. The immediate use-cases are clothes with built-in sensors (think radiation or heartbeat monitors), but ultimately, think of how many thousands of interconnections are in every piece of cotton clothing — you could make a fairly powerful computer!"
