Abstract
A gas sensor with an integrated preconcentrator is disclosed. The gas sensor may comprise: a preconcentration unit comprising a material that adsorbs a predetermined target gas, and configured to adsorb the target gas under predetermined adsorption conditions and/or release the adsorbed target gas under predetermined release conditions; a sensing unit adjacent to the preconcentration unit and configured to sense at least the target gas released by the preconcentration unit; and a preconcentration control unit configured to control satisfaction or non-satisfaction of the adsorption conditions and/or the release conditions.
Claims17
A gas sensor comprising:
- a preconcentration unit comprising a material that adsorbs a predetermined target gas, and configured to adsorb the target gas under predetermined adsorption conditions and/or release the adsorbed target gas under predetermined release conditions;
- a sensing unit adjacent to the preconcentration unit and configured to sense at least the target gas released by the preconcentration unit;
- and a preconcentration control unit configured to control satisfaction or non-satisfaction of the adsorption conditions and/or the release conditions.
A low-concentration gas sensing method comprising:
- providing a gas sensor comprising:
- a preconcentration unit comprising a material that adsorbs a predetermined target gas, and configured to adsorb the target gas under predetermined adsorption conditions and/or release the adsorbed target gas under predetermined release conditions;
- a sensing unit adjacent to the preconcentration unit and configured to sense at least the target gas released by the preconcentration unit;
- and a preconcentration control unit configured to control satisfaction or non-satisfaction of the adsorption conditions and/or the release conditions;
- and sensing, through the sensing unit, the target gas that the preconcentration unit releases after adsorption.
A gas monitoring device comprising:
- a gas sensor comprising:
- a preconcentration unit comprising a material that adsorbs a predetermined target gas, and configured to adsorb the target gas under predetermined adsorption conditions and/or release the adsorbed target gas under predetermined release conditions;
- a sensing unit adjacent to the preconcentration unit and configured to sense at least the target gas released by the preconcentration unit;
- and a preconcentration control unit configured to control satisfaction or non-satisfaction of the adsorption conditions and/or the release conditions;
- and a signal generation unit configured to generate a signal when the gas sensor detects the target gas at or above a predetermined level.
