Abstract
A sensor is provided with (i) a pair of electrically conducting electrodes on an electrically insulating substrate; (ii) a chemiresistor film in contact with the pair of electrodes, with an impedance that changes in the presence of an ionic analyte; (iii) a gate electrode formed from an electrically conductive material; (iv) a potential generator configured to apply an electrical potential difference between the gate electrode and the chemiresistor film; (v) a controller to selectively control the potential generator to apply an electric potential to the gate electrode relative to the potential of the chemiresistor film; and (vi) a voltage power source adapted to apply a voltage signal between the pair of electrically conducting electrodes to enable measurement of the resistance of the chemiresistor film.
