Sensor Design Principles

The basic zirconia oxygen sensor design is illustrated in Fig. 13.52, which shows the principle of the zirconia solid oxygen-ion electrolyte. The sensor consists of a closed-end tube of ceramic zirconia ZrO )). The zirconia ceramic...

Improvement and optimization of the characteristics of the existing sensors is an important work that is constantly been addressed by many research groups, and is briefly reviewed here. The rational molecular design principles become important to the search for new sensor materials to be more selective and sensitive, possess better detection limits,... 

We have shown that antiresonant dielectric layers can be used to design low-loss liquid-core waveguides that are suitable for implementing planar sensor device geometries. The following sections will describe in more detail how the design principles laid out here were implemented in silicon-based LC-ARROW chips and used for optical sensing and detection of a wide variety of substances. 

The same design principles apply to the magnesium sensors PET-15 and PET-16, in which the recognition moiety has a smaller cavity . 

In Chapter 10, fluorescent pH indicators and fluorescent molecular sensors for cations, anions and neutral molecules are described, with an emphasis on design principles in regard to selectivity.

Differences between both tests result from the different test principles. Biosensors use either a pure culture of microbes or a defined combination of several species of microorganisms with a fixed metabolic state, whereas for the conventional method an undefined bacterial population derived from activated sludge is used. In Sect. 3.2.1.3 it is shown that this obstacle can at least partly be overcome by the selection of suitable microorgaiusms for the BOD-sensor design. 

Design principles of new sensors for ionic drugs follow from application of potential gjnerjtion theory using three ions M, X and Y, or M, N and Y. Studies of liquid/liquid interface transport identify single-ion free energies of partition as the figures of merit for selectivity and sensitivity. New liquid membranes with sensitivities to 10 mol/1 for bisquaternary muscle relaxants and phenytoin serve as examples. 

The interplay of mass transfer, partition and enzymatic substrate conversion determines the dynamic measuring range, response time, and accessibility towards interferences of enzyme sensors. New principles for designing the analytical performance by coupled enzyme reactions are presented in this paper ... 

Some studies were devoted to Tm3+-doped fluoride fibers for hydrocarbon gas sensing, especially CH4 with respect to safety issues. A special laser cavity was designed in order to take maximum advantage of the broad tunability of the 3H4 - 3H5 transition of Tm3+ around 2.3 /un. A flat laser output power could be achieved over the 2.3-2.4 pm range where methane shows two strong absorption peaks. The sensor, whose principle is based on the direct absorption of laser light... 

The first practical problem to be addressed is the fabrication of acoustic-wave sensor devices. While some devices are commercially available (see Appendix D), a researcher may need a unique device in order to investigate some previously unexplored aspect of AW sensors and their interactions with their environment. It is therefore quite valuable to understand basic device configurations, fundamental design principles, the different properties of the range of materials that can serve as device substrates, fabrication practices, and coating technologies. These issues are addressed in Section 6.2.
