The way in which OECTs communicate-using ions, just as biology does-may also open up applications such as biomedical sensing, body-machine interfaces, and brain-imitating neuromorphic technology. Organic electronics have a number of advantages over their standard counterparts, such as flexibility, low weight, and easy, cheap fabrication. “Our vertically stacked electrochemical transistor takes performance to a totally new level.” -Tobin Marks, Northwestern University This feature helps make OECTs efficient switches and powerful amplifiers. Whereas organic field-effect transistors (OFETs) have ions that accumulate only on the surface of the organic material, organic electrochemical transistors (OECTs) rely on ions flowing in and out of organic semiconductors. Most transistors are made of inorganic semiconductors, but organic electronics depend on organic compounds. Modern electronics rely on transistors, which are essentially switches that flick on and off to encode data as ones and zeros. Now scientists have created record-breaking, high-performance organic electronic devices using a potentially cheap, easy, and scalable approach that adopts a vertical architecture instead of a flat one, according to a new study. Organic electronics appear to be, as the name might imply, quite good at interacting with a biological body and brain.
