Written by an interdisciplinary group of experts from both industry and academia, Acoustic Wave Sensors provides an in-depth look at the current state of acoustic wave devices and the scope of their use in chemical, biochemical, and physical measurements, as well as in engineering applications. Because of the inherent interdisciplinary applications of these devices, this book will be useful for the chemist and biochemist interested in the use and development ofthese sensors for specific applications; the electrical engineer involved in the design and improvement of these devices; the chemical engineer and the biotechnologist interested in using these devices for process monitoring and control; and the sensor community at large. Provides in-depth comparison and analyses of different types of acoustic wave devices Discusses operating principles and design considerations Includes table of relevant material constants for quick reference Presents an extensive review of current uses of these devices for chemical, biochemical, and physical measurements, and engineering applications

This book concerns the design, operation and application of devices capable of generating acoustic waves in the ultrasonic frequency range. It emphasizes the study of chemical and/or biochemical systems imposed on the surface of such devices, whether operated in the gas- or liquid-phase, i.e. on acoustic wave chemical and biological sensors. It focuses on devices that employ acoustic waves launched and received on the same surface. It touches upon such diverse areas as acoustic wave physics, applied mathematics, chemistry, electronics, fluid mechanics, materials science and polymer science.

There were two reasons that induced me to plan and to organize this book, the first was the lack of a text entirely devoted to the subject of gas sensors, notwithstanding some books devoted to the various kind of chemical sensors have recently been published. The second reason was the need of introducing the basic topics of gas detection mechanisms to a growing number of researchers active in research and development laboratories of industries and uni versities. The field of chemical sensors is indeed in fast and consistent growth, as it is proved by the increased number of participants to the congresses that were recently held on this subject, namely the Third Meeting on Chemical Sensors (September 24 - 26, 1990, Cleveland), Transducers' 91 (June 24 - 27, 1991, S. Francisco) and EUROSENSORS V (September 30 - October 3, 1991, Rome). Therefore, this book is mainly intended as a reference text for researchers with a MS degree in physics, chemistry and electrical engineering; it reports the last progresses in the R. & D. and in the technology of gas sensors. I choose to deal specifically with the topic of gas sensors because these devices show a very large number of applications in the domestic and industrial field and they are characterized by a great effort of research and development.

Acoustics is a mature field which enjoys a never ending youth. New developments are induced by either the search for a better understanding, or by technological innovations. Micro-fabrication techniques introduced a whole new class of microdevices, which exploit acoustic waves for various tasks, and in particular for information processing and for sensing purposes. Performance improvements are achievable by better modelling tools, able to deal with more complex configurations, and by more refined techniques of fabrication and of integration in technological systems, like wireless communications. Several chapters of this book deal with modelling and fabrication techniques for microdevices, including unconventional phenomena and configurations. But this is far from exhausting the research lines in acoustics. Theoretical analyses and modelling techniques are presented, for phenomena ranging from the detection of cracks to the acoustics of the oceans. Measurement methods are also discussed, which probe by acoustic waves the properties of widely different systems.

We present an experimental study of mass sensitivity for a Surface Acoustic Wave (SAW) sensor. Chemical SAW sensors have been developed to detect the mass variation of the mass adsorbed into sensing film by showing resonant frequency shifts. Previous experimental results have focused on the static sensitivity of theoretical SAW sensors assuming that the film thickness is negligible compared to the central wavelength of surface waves. Most current research is focused on dynamic experimental measurement and analytical techniques that are application specific. We have studied a SAW sensor with relatively thick isotropic film layers sputtered on as a static measurement comparison. The results can be used in a detection algorithm to quantify mass on the SAW sensor. Our results show a set of nodal response wave form changes and frequency shifts due to a continuous mass distribution. The development of the static experimental technique was completed with duplicate SAW tests. The duplicate SAWs had 12 measurements with 10 independently sputtered layers of 100 m SiO 2 , hermitically sealed, and hermitical seal removed using a HP8510A network analyzer. In addition, our results show worst case total error of 0.1% between replicates. Further testing and modeling is required to correlate macro to micro scales for quantifying mass detection with SAW sensors. This research discusses the issues of utilizing a SAW sensor that could be readily integrated into cell phones for distributed sensing as being requested by Homeland Security.
