摘要： An embodiment of the invention is an organic thin film transistor chemical sensor. The sensor includes a substrate. A gate electrode is isolated from drain and source electrodes by gate dielectric. An organic ultra-thin semiconductor thin film is arranged with respect to the gate, source and drain electrodes to act as a conduction channel in response to appropriate gate, source and drain potentials. The organic ultra-thin film is permeable to a chemical analyte of interest and consists of one or a few atomic or molecular monolayers of material. An example sensor array system includes a plurality of sensors of the invention. In a preferred embodiment, a sensor chip having a plurality of sensors is mounted in a socket, for example by wire bonding. The socket provides thermal and electrical interference isolation for the sensor chip from associated sensing circuitry that is mounted on a common substrate, such as a PCB (printed circuit board). A method of operating an organic thin film transistor chemical sensor exposes the sensor to a suspected analyte. A low duty cycle voltage pulse train is applied to the gate electrode to reduce baseline drift while sensing for a conduction channel change.
