This work presents a first approach to the fabrication of room temperature floating gate GasFETs based on the readout of the work function of conductive polypyrrole (PPy) coatings. PPy coatings have been fabricated onto Au and Pt coated alumina substrates by means of the in-situ polymerization technique. The response of the coatings to different gases and volatile organic compounds (VOCs), such as ethanol, acetone, methylamine or isopropanol and gases has been tested using the Kelvin...
