Opis

In recent years, there has been a convergence of fundamental materials science and materials processing methods. This convergence, although highly interdisciplinary in nature, has been brought about by technologies such as bandgap engineering and related techniques that have led to application-specific devices such as lab-on- chip and system-on-a-chip. The demand for reduced device size, device portability, and low power dissipation coupled with high speed of operation continues to dictate terms and conditions for the evolution of nanotechnology. The present trend in approaches to systems manufacturing continues to focus on integration of mul- functionalities on the same chip. These functionalities include, for example, - board laser sources, sensors, and amplifiers. Both the military and civilian markets continue to drive the research and development component. In recent years, the emergency preparedness guidance systems have added excitement and curiosity to this expanding industry. The outgrowth of technologies of interest for emergency preparedness includes the development of terahertz sources and detectors and s- tems for detection of explosives and concealed weapons, among others. Sensors made from bulk materials have been around for a long time. Enormous advances in the processing technologies of thin films have led to the ability to manufacture application-specific functional thin films.

Thin films and nanostructures can play multiple roles in a sensor including structural support, reliability enhancement, filtering and transduction. These micro and nano structured materials are discussed here in the context of transduction and how they contribute to the current sensor revolution. This book covers an account of general sensors theory, design considerations, and specific case studies of functional thin films and nanostructure applications in sensing as it demonstrates the whole design process. The book is also intended to provide the more experienced designers with a condensed summary of sensor design methodology and excellent references that will prove useful in future sensor design endeavors. This book is also of interest to those with a deep knowledge of such areas of science and engineering as materials science, physics, chemistry, biology, mechanical and electrical engineering.
