Fiber Optic Sensors For Biomedical Applications

This authoritative new resource presents fiber optic sensors and their applications in medical device design and biomedical engineering. Readers gain an understanding of which technology to use and adopt, and how to connect technologies with their respective applications. This book explores the innovation of diagnostics and how to use diagnostic tools. Principles of fiber optic sensing are covered and include details about intensity-based sensors, fiber bragg gratings, distributed sensors, and fabry-perot interferometers. This book explores interrogation software, standards for medical sensors, and discusses protocols and tools for validation. Various medical device engineering and applications are examined, including sensor catheterization, cardiovascular sensors, diagnostic in gastroscopy, urology, neurology, sensing in thermal ablation. Applications and detection of SPR sensors are presented, along with minimally invasive robotic surgery, smart textiles, wearable sensors and fiber-optic spectrometric sensors. This is a one-stop reference on fiber optic sensors for biomed applications.

This book describes important recent developments in fiber optic sensor technology and examines established and emerging applications in a broad range of fields and markets, including power engineering, chemical engineering, bioengineering, biomedical engineering, and environmental monitoring. Particular attention is devoted to niche applications where fiber optic sensors are or soon will be able to compete with conventional approaches. Beyond novel methods for the sensing of traditional parameters such as strain, temperature, and pressure, a variety of new ideas and concepts are proposed and explored. The significance of the advent of extended infrared sensors is discussed, and individual chapters focus on sensing at THz frequencies and optical sensing based on photonic crystal structures. Another important topic is the resonances generated when using thin films in conjunction with optical fibers, and the enormous potential of sensors based on lossy mode resonances, surface plasmon resonances, and long-range surface exciton polaritons. Detailed attention is also paid to fiber Bragg grating sensors and multimode interference sensors. Each chapter is written by an acknowledged expert in the subject under discussion.

Optical Fiber Biosensors: Device Platforms, Biorecognition, Applications provides a comprehensive overview of the field of fiber optic sensors using an interdisciplinary approach that covers the fabrication of sensing devices and optical hardware, the functionalization to perform selective biorecognition, and the main applications of biosensors, with a present and a future outlook. Chapters discuss the principles of light propagation and the sensing devices suitable to perform biosensing with optical fibers, the process to functionalize the previous devices to selective biosensing, and applications in cells, small molecules, biomarkers and protein sensing, with a birds eye view on the most important results. This book provides a coherent picture of fiber optic biosensors, from the start (the device) to the end (the application), explaining in simple terms what is the whole process for development of a biosensor. The book also contains practical material (e.g. commercial instruments, fabrication instructions, medical standards for biocompatibility) that cannot be easily found elsewhere, and this is very useful for researchers to plan their development and build their labs. Covers the technologies and operating principles of optical fiber devices used in biosensing Contains chapters on the chemistry and operational strategy to functionalize a fiber device to become an effective biosensor Addresses the main applications of fiber optic biosensors and their specialization

Since the technology has moved strongly into a number of different areas a textbook of this sort could be used by a wide variety of academic departments including physics, electrical engineering, mechanical engineering, civil engineering, aerospace engineering and bioengineering. To make the second edition as widely appealing as possible a series of significant upgrades were made. 1. The book is structured to support a variety of academic programs and it can also be used as a general reference by practicing engineers and scientists. 2. The introductory chapter has been revised to outline the new content of the second edition and provide a overview of the current status of fiber optic sensor technology. 3. A new, extensive chapter has been added covering fiber optic grating sensor technology and its application to aerospace, civil structures, oil and gas and power generating applications. 4. A second new chapter has been added on the emerging field of biomedical fiber optic sensors. This is one of the most rapidly growing fields of use for fiber optic sensors and with rising health costs and medical advances promises to be an important area for many years to come.

Due to recent advances in technology, optical fibers have opened their ways into the sensing industry. Various sectors are the major targets for optical fiber sensors capable of measuring mechanical parameters such as pressure, stress, strain, temperature, and others. Opto-mechanical fiber optic sensors provide unique advantages unbeatable by other sensing systems. These advantages, to name a few, are immunity to electromagnetic interference, high fidelity and signal to noise ratio, low-loss remote sensing, and small size. These sensors already have proven track record of success in industry The first part of the book brings the readers all needed background information on the theoretical aspects of FOS as well as fabrication and packaging methods. On de second part, the Editor selected a full range of current and emerging applications in Mechanical, Oil & Gas, Biomedical and Biomechanical, Aerospace and Automotive industries. Special attention is also given to FOS applications to sensing in harsh environments. Provide current background information and fundamentals to Fiber Optic sensors Technology Bring a wide variety of established and emerging applications of FOS Focus on Mechanical parameter measurement Contributions of leading researchers and practitioners in their fields Coverage of current methods of fabrication and packaging

While most books contain some information on related sensors topics, they are limited in their scope on biomedical sensors. Sensors in Biomedical Applications: Fundamentals, Design, Technology and Applications is the first systematized book to concentrate on all available and potential sensor devices of biomedical applications! Sensors in Biomedical Applications presents information on sensor types in a comprehensive and easy to understand format. The first four chapters concentrate on the basics, lending an understanding to operation and design principles of sensor elements. Introduced are sections on: basic terms, sensor technologies, sensor structure and sensing effects. The next three chapters describe application possibilities: physical sensors, sensors for measuring chemical qualities and biosensors. Finally, a chapter covers biocompatability, in addition to an appendix and glossary. Sensors in Biomedical Applications is the definitive reference book for a broad audience. All physicists, chemists and biologists interested in the chemical basis and effects of sensors will find this work invaluable. Biomedical engineers and sensor specialists will find the text useful in its pointed analysis of special design, processing and application problems. Physicians practicing with diagnostic tools will want to see the possibilities and limits of biomedical sensors. Finally, students of all of the above areas who wish to learn more about the basics of biomedical sensors need to have this book.

The material in this book is based upon a two-day workshop on solid state physical sensors for biomedical applications held in Huron, Ohio, December 8-9, 1977. The individual sections of the book are based upon presentations made by the authors at the workshop. Each presentation was transcribed and given to the authors for revision. Also, transcribed, are the discussions had following each presentation.
