Demand for sensitive, stable and durable gas sensor technology is rising continuously - but sensors available on the market to date are generally unable to meet all three requirements in equal measure. Fraunhofer EMFT scientists are working on optimized solutions for chemical gas sensors, for example for CO2. One aim is to gain a better understanding of sensor properties in order to be able to select the most suitable sensors for specific applications. In addition, the team is working on the development of novel gas sensors that go beyond the current state of the art. Close cooperation with industrial partners enables fast transfer of new findings to the market.
