A device for providing a calibration fluid, in particular a nitrogen oxide, for calibrating a respiratory gas analysis device, includes a first interface for connecting a chamber of the device to a measurement path of the respiratory gas analysis device, a first opening for introducing a reactant carrier with a first reactant into the chamber, and a contact element. The contact element is arranged in the chamber relative to the first opening such that when the reactant carrier is introduced, a contact of the contact element with the reactant carrier is facilitated in order to trigger a chemical reaction of the first reactant so as to generate the calibration fluid. The disclosure further relates to a system, a reactant carrier, and a method for providing a calibration fluid for calibrating a respiratory gas analysis device.

A sensor system for detecting a leak of a system component from an electrochemical storage system, in particular a lithium-ion battery. To determine a defect in the electrochemical storage system, the sensor system includes a reaction chamber containing a detection component, and a measuring device for determining a physical variable within the reaction chamber. The value of the physical variable is changeable by a chemical reaction of the system component with the detection component, so that a leak of the system component is detectable via a change in the value of the physical variable. Also described is a sensor element for such a sensor system, an electrochemical storage system having such a sensor system or sensor element, the use of such a sensor system or sensor element, and a mobile or stationary system, for example an electric vehicle, equipped with the sensor system, the sensor element, or the storage system.

The invention relates to a method for localizing a defect in an electrochemical store (). The method includes a step of controlling the temperature of a subarea () of the electrochemical store () to increase an internal pressure of the subarea (), a step of detecting a measured value which represents an escape of a component from the subarea () occurring in response to the increased internal pressure of the subarea (), and a step of localizing the defect in the subarea () when the measured value is in a predetermined relation to a comparison value.

A microelectrochemical sensor includes an energy supply unit and a sensor unit. The energy supply unit is configured to generate electrical energy using a reference fluid. The sensor unit is configured to determine a concentration difference of a chemical species between a measuring fluid and the reference fluid. The measuring fluid has an unknown concentration of the species, and the reference fluid has a known concentration of the species. The sensor unit is electrically connected to the energy supply unit and is designed to determine the concentration difference using the electrical energy from the energy supply unit.

A sensor device for sensing a gas includes a sensing region, and a readout region that is electrically and mechanically connected to the sensing region by way of a connecting web. The readout region, the sensing region, and the connecting web are formed from a substrate, and are isolated from the substrate by a clearance cutout. The sensing region has an ion-conducting region configured to provide a measuring signal dependent on the gas. The readout region (is configured to read out the measuring signal.

A microelectrochemical sensor having a diaphragm, a web, a first and a second electrode. The diaphragm is permeable to ions of a chemical species, is arranged transversely with respect to a cutout in a base body, and closes off the cutout in a fluid-tight fashion. The web is arranged on a first side of the diaphragm between a first partial surface and a second partial surface, and is designed to adjust a temperature of the diaphragm to an operating temperature using electrical energy. The first electrode has a first partial electrode and a second partial electrode, is permeable to fluid, and is arranged on the first side of the diaphragm. The web prevents electrical contact between the first electrode and the diaphragm. The second electrode has a third partial electrode and a fourth partial electrode, is also permeable to fluid, and is arranged on a second side of the diaphragm.
