Abstract in another language

Gas sensors are widespread in our technical world. The applications cover areas like safety and security, emission control and immission monitoring, process control and many more. Mostly, the gas sensors are operated at temperatures above 350 °C, and hence, have to be manufactured in a high temperature compatible technology - in ceramic technology. Two fields of application for ceramic multilayer gas sensors are reviewed: zirconia based hightemperature co-fired lambda sensors including their direct derivatives for exhaust gas sensing and the LTCC-based approaches for novel transducers for high temperature gas sensors. Today’s stabilized zirconia based planar automotive exhaust gas sensors are manufactured in combined tape and thick-film technology that resembles microelectronic hybrid technology. Their multilayer set-up serves as a basis not only for conventional potentiometric lambda probes or amperometric wide band lambda probes but also for novel NOx sensors or ammonia sensors. Up to now, LTCC-based transducers for gas sensors are in the research state. Based on the ideas of suspended beam hot plates, they offer the chance to implement a fully ceramic chip that consumes only low power and that does not need high temperature wire bonds.
