A method of sensing a target gas in an environment in which a response of a semiconducting gas sensor device upon exposure to the environment is measured. The semiconducting gas sensor device includes first and second electrodes in electrical contact with a doped organic semiconductor layer and is, e.g., an organic thin film transistor or organic chemiresistor. The measured response may be indicative of a cumulative amount of a target gas that the semiconducting gas sensor device has been exposed to. A gas sensor module containing the semiconducting gas sensor device may be connectable to a reader configured to read the semiconducting gas sensor device after exposure to the environment. The connection may be wired or wireless. The target gas may be 1-methylcyclopropene.
A method of sensing a target gas in an environment, the method comprising measuring a response of a semiconducting gas sensor device upon exposure to the environment, the semiconducting gas sensor device comprising first and second electrodes in electrical contact with a doped organic semiconductor layer, wherein the measured response is indicative of a cumulative amount of the target gas that the semiconducting gas sensor device has been exposed to.
Gas sensor apparatus comprising a gas sensor module and a reader module connectable to the gas sensor module wherein the gas sensor module comprises a semiconducting gas sensor device comprising first and second electrodes in electrical contact with a doped organic semiconductor layer and wherein the reader module is configured to measure a parameter of the semiconducting gas sensor device upon connection to the gas sensor module.
