Finally as the last example of scientific thin film applications sensor devices will be discussed. Thin film thermocouples and thin film bolometers are often applied in scientific experiments to measure and to control the surface temperature, e. g. [242]. These rather simple thin film devices are complemented today by various other,...

In this paper, we present the structure and shape of the new thin-film pressure sensor and results of oil-film pressure distribution measured in an engine main betuing and in a piston pin-boss. In addition, a new sensor structure is reported, using aluminum-nitride to reduce the temperature dependence of pressure sensitivity in high temperature range.

Low temperature sol-gel technology is promising approach for preparation of modified with organic molecules silica (SG) thin films. Such films are perspective as sensitive elements of optical sensors. Incorporation of polyelectrolytes into SG sol gives the possibility to obtain composite films with ion-exchange properties. The addition of non-ionic surfactants as template agents into SG sol results formation of ordered mechanically stable materials with tunable pore size. 

The chemical and electronic properties of elements at the interfaces between very thin films and bulk substrates are important in several technological areas, particularly microelectronics, sensors, catalysis, metal protection, and solar cells. To study conditions at an interface, depth profiling by ion bombardment is inadvisable, because both composition and chemical state can be altered by interaction with energetic positive ions. The normal procedure is, therefore, to start with a clean or other well-characterized substrate and deposit the thin film on to it slowly at a chosen temperature while XPS is used to monitor the composition and chemical state by recording selected characteristic spectra. The procedure continues until no further spectral changes occur, as a function of film thickness, of time elapsed since deposition, or of changes in substrate temperature. 

The gas-sensitive material in thick-film gas sensors has a sintered layer area of a few square millimeters, and about 30 im in thickness, on a ceramic substrate (Fig. 13.546). In other types of gas sensors, it is on the outer surface of a thin tube or as a sintered button (Fig. 13.54l and c). The sensor is heated tet the operating temperature of 300-500 °C by means of a resistor. 

GP 1] [R 10] By proper heater design, membrane-based reactors with internal heaters allowed one to reach quasi-uniform temperatures at the membrane, which determines the catalyst temperature [19]. This thermal uniformity was checked during reaction, i.e. when large heats were released in the oxidation of ammonia and needed to be transferred out of the reaction zone (Figure 3.29). Thin-film-coated temperature sensors in the center and at the edges of the membrane served to monitor the lateral temperature difference.
