We present the design and fabrication of a chemoresistive sensor array for the volatile organic compounds and gas detection. Different nanofibrous conductive polymers, produced by electrospinning technique, have been used as chemical interactive materials. Sensor array was integrated with read-out electronic circuits on flexible substrate. In order to obtain high electrical performances maintaining integration capability, on plastic materials, respect to standard c-Si CMOS technology, polycrystalline silicon thin film transistor based circuitry has been used. The performances of the fabricated sensor array have been tested with different concentrations of methanol, lactic acid and ammonia.
