History has shown that advancements in materials science and engineering have been important drivers in the development of sensor technologies. For instance, the temperature sensitivity of electrical resistance in a variety of materials was noted in the early s and was applied by Wilhelm von Siemens in to develop a temperature sensor based on a copper resistor. The high resonance stability of single-crystal quartz, as well as its piezoelectric properties, have made possible an extraordinarily wide range of high performance, affordable sensors that have played an important role in everyday life and national defense. More recently, a new era in sensor technology was ushered in by the development of large-scale silicon processing, permitting the exploitation of silicon to create new methods for transducing physical phenomena into electrical output that can be readily processed by a computer. Ongoing developments in materials technology will permit better control of material properties and behavior, thereby offering possibilities for new sensors with advanced features, such as greater fidelity, lower cost, and increased reliability. To provide a foundation for its recommendations in these areas, the committee began by assessing the current status of sensor technologies. Early in this assessment, the committee found that applications, not materials, drive new sensor development. Therefore the committee identified a conceptual framework that could relate sensor materials to application needs within which the importance of particular sensor materials could be determined. Given the extensive body of published work relating to the broad, multidisciplinary subject of sensor technologies, the committee prepared a summary bibliography drawn from the recent literature Appendix A. The bibliography includes review articles, books, and monographs relating to the wide range of sensor technologies. These references can form a basis from which a more detailed study of any particular sensing technology, principle, or application can be initiated. Several key journals dealing with sensing have been included in the bibliography; they are suggested as starting points for investigating the most recent developments and trends in sensor technologies. Additional information is available from the reference list at the end of each chapter. Despite the extensive published literature that treat the fundamentals of sensor technology, considerable ambiguity exists in sensor definition and classification, as illustrated by a recent buyer's. The latter list includes both physical phenomena for example, acoustic, electrochemical, Hall effect and infrared sensorsand material types such as bimetallic, fiberoptic, thick-and thin-film, and zirconium oxide sensors. Understanding the physical or chemical effects that yield useful transduction is important in selecting and designing sensors. However, these effects by themselves are usually not sufficient to establish an unambiguous sensor classification, since typical sensors may use more than one effect. A simple example is a diaphragm pressure gauge. The diaphragm uses one form of mechanical energy to create another pressure generates displacement and strain ; however, the creation of an electrical signal from the displacement or strain can be accomplished using many approaches. The diaphragm could be made of a piezoelectric material, in which the air would induce an electrical charge; an inductive or capacitive effect could be employed to measure the charge related to the strain and the deflection and thereby infer the pressure. Thus understanding all of the possible field effects and features of transducer materials behavior provides the most complete set of sensor design options. In order to accelerate the incorporation of emerging sensor materials in new applications, it is critically important that the sensor materials community be able to readily identify sensing needs that candidate materials could fulfill. The formal study of sensor technology is plagued by ambiguity in definitions and terminology. This evolving field of endeavor is extraordinarily broad with nearly every scientific and technical discipline playing an important role.
