Entwicklung und Anwendung von Hochdurchsatztechniken zur Darstellung und Untersuchung neuer nanostrukturierter Sensormaterialien
For the development of new gas sensor materials surface and volume doped nanoscalic metal oxides were investigated, whereas high-throughput techniques were applied. The necessary synthesis and characterisation methods were provided by modification of a pipetting robot for a parallel material …

Untersuchungen zur Modellierung und Optimierung von Oberflächenwellen-Bauelementen und Auswerteschaltungen für die Gassensorik
This work describes the application of polymer coated surface acoustic wave (SAW) devices as gas sensors. It focuses on the characterization and modelling of SAW resonators. Additionally SAW delay lines and thickness shear mode devices are described. The major effects of the sorption of gas …

Entwicklung eines langzeitstabilen Niedrigenergie-IR-Gassensors
Within this dissertation two new measurement-techniques which reduce the power-consumption of an infrared-gas-sensor (IR) are introduced. By using the maximum of the sensor-signals first derivative, the author was able to reduce the power-consumption of an carbon-dioxide-sensor (CO2) for …

Untersuchungen zum Betriebsverhalten temperaturregelbarer OFW-Gassensoren
Generally Surface Acoustic Wave (SAW) gas sensors are based on piezoelectric crystals like silicon oxide or lithium niobate and are often manufactured with a complicated technology. In order to reach high temperature stability, special crystal cuts are used. These cuts often show a small …
