摘要： A gas sensor has at least one gas sensitive layer, which has at least one surface area in which the work function is dependent upon the concentration of a target gas capable of being brought into contact with the surface zone. At least one electric potential sensor is capacitatively coupled to the surface zone over an air gap. The surface zone of the gas sensitive layer is covered with an electrically insulating coating which is inert to the target gas and which is adhesively bound to the gas sensitive layer. The coating is configured so that it is permeable to the target gas and so that when the target gas contacts the surface zone of the gas sensitive layer, it prevents or at least impedes an alteration of the bound state of atoms and/or molecules bound to the surface zone and differing from the target gas.

摘要： A device for detecting a gas or gas mixture has a first and a second gas sensor. The first gas sensor is a MOSFET, which comprises a first source, a first drain, a first channel zone disposed between the latter elements, and a first gas sensitive layer capacitively coupled to the first channel zone that contains palladium and reacts to a change in the concentration of the gas to be detected with a change in its work function. The second gas sensor has, in a semiconductor substrate, a second source, a second drain, and a second channel zone between the latter elements, which is capacitively coupled via an air gap to a suspended gate. The latter comprises a second gas sensitive layer that reacts to a change in the concentration of the gas to be detected with a change in its work function. The second gas sensitive layer is arranged on a support layer and faces the air gap. The support layer is formed by another semiconductor substrate, and the first gas sensor is integrated in the front side of the second semiconductor substrate facing away from the air gap.

摘要： A gas sensor has a gas-sensitive layer with a surface area where the electron affinity depends on the concentration of a target gas brought in contact with the surface area. An electrical potential sensor is capacitively coupled to the surface area via an air gap. The surface area of the gas-sensitive layer is covered by an electric insulating layer that is inert to the target gas and is bonded to the gas-sensitive layer. The coating is designed in such a way that it is permeable for the target gas and a different, non-target gas that can be adsorbed on the surface area. The coating has different diffusion constants for the target gas and the non-target gas. The diffusion constants are coordinated with each other in such a way that the sensitivity of the gas sensor to the target gas increases when the target gas concentration exceeds a predetermined concentration threshold in the presence of the non-target gas.

摘要： In a procedure for measuring the concentration of a target gas, a gas sensor is provided whose sensor signal at constant temperature is dependent on a target gas concentration and has a lower measurement sensitivity in a first modulation range than in a second modulation range. The position of the modulation ranges is dependent on the temperature. The temperature of the gas sensor is controlled so that the sensor signal is essentially independent of the target gas concentration and lies within the second modulation range. The temperature of the gas sensor is then a measurement for the target gas concentration.
