Organic Electrochemical Transistors for Biosensor and ioelectronic Applications

Organic electrochemical transistors (OECTs) are emerging as important rival in the field of organic bioelectronics. The core of OECT devices is an organic conducting polymer channel, defined by source and drain electrodes, ionically connected to the gate electrode via an
electrolyte solution. Prior to the application of gate voltage (Vgs) the source-drain current measured upon application of a drain-source voltage only depends on the intrinsic conductance of the polymer. Upon application of Vgs some of the electrolyte enter the polymer channel and
dope or dedope it, thus leading to channel current modulation. Hence OECTs can be used as converters between ionic currents in the electrolyte and electronic currents in the organic channel and this mechanism ultimately opens the door of OECTs for sensor application. In this project we will introduce new conducting polymer for the first time as electroactive material for OECTs application.
