Gas ionization sensor comprising at least one sensing element on a substrate. The sensing element comprises: at least one nanowire; a counter electrode which surrounds the nanowire, the surrounding electrode being electrically isolated from the nanowire and being at a predetermined gap from the nanowire, the gap allowing penetration of a gas or a gas mixture between the nanowire and the surrounding electrode; a voltage source electrically connected between the nanowire and the surrounding electrode for providing a voltage difference between the nanowire and the surrounding electrode; and measurement circuitry for measuring a breakdown voltage and/or an electrical discharge current and/or a prebreakdown current through the gap. |
