  • Fiber-based organic electrochemical transistor
    Patent number: 9178170
    Abstract: An organic electrochemical transistor (OECT) that may be used as a biosensor is built up by layers applied to a monofilament. A first conducting layer applied to the monofilament includes generally cylindrical source and drain contacts with a gap therebetween. An electro-active layer of an organic material altering its electrical conductivity through a change in redox state is in electrical contact with the source and drain contacts, and has a transistor channel interface for contacting an electrolyte. A gate electrode is spaced apart from the first monofilament, and may comprise a cylindrical layer built up on another length of monofilament.
    Type: Grant
