Ultra Low Power Bioelectronics (eBook, PDF)

Fundamentals, Biomedical Applications, and Bio-Inspired Systems

• Format: PDF

Produktbeschreibung

This book provides, for the first time, a broad and deep treatment of the fields of both ultra low power electronics and bioelectronics. It discusses fundamental principles and circuits for ultra low power electronic design and their applications in biomedical systems. It also discusses how ultra energy efficient cellular and neural systems in biology can inspire revolutionary low power architectures in mixed-signal and RF electronics. The book presents a unique, unifying view of ultra low power analog and digital electronics and emphasizes the use of the ultra energy efficient subthreshold regime of transistor operation in both. Chapters on batteries, energy harvesting, and the future of energy provide an understanding of fundamental relationships between energy use and energy generation at small scales and at large scales. A wealth of insights and examples from brain implants, cochlear implants, bio-molecular sensing, cardiac devices, and bio-inspired systems make the book useful and engaging for students and practicing engineers.

Autorenporträt

Rahul Sarpeshkar leads a research group on bioelectronics at the Massachusetts Institute of Technology (MIT), where he has been a Professor since 1999. This book is based on material from a course that Professor Sarpeshkar has taught at MIT for 10 years, where he has received both the Junior Bose Award and the Ruth and Joel Spira Award for excellence in teaching. He has won several awards for his interdisciplinary bioengineering research including the Packard Fellow Award given to outstanding faculty.

Inhaltsangabe

Part I. Foundations: Ten chapters lay a foundation in device physics,
noise, and feedback systems including nano scales in a highly original
fashion, emphasizing intuitive thinking. This foundation is important in
designing and analyzing ultra-low-power systems in both electronics and
biology; Part II. Low-Power Analog and Biomedical Circuits: Five chapters
present building-block circuits that are useful for ultra-low-power
biomedical electronics and analog electronic systems in general; Part III.
Low-Power RF and Energy-Harvesting Circuits for Biomedical Systems: Three
chapters provide an in-depth description of energy-efficient power and data
radio-frequency (RF) links that are fundamental to biomedical systems; Part
IV. Biomedical Electronic Systems: Two chapters provide an in-depth look at
ultra-low-power implantable electronics and ultra-low-power noninvasive
electronics for biomedical applications, respectively. Case studies for
cochlear implants for the deaf, brain implants for the blind and paralyzed,
wearable cardiac devices, and biomolecular sensing are provided; Part V.
Principles for Ultra-Low-Power Analog and Digital Design: Two chapters
discuss principles for ultra-low-power digital design and ultra-low-power
analog and mixed-signal design, respectively. The chapters identify ten
fundamental principles that are common in both biology and electronics,
analog and digital design; Part VI. Bio-Inspired Systems: A chapter on
neuromorphic electronics discusses electronics inspired by neurobiology
followed by a chapter that discusses a novel form of electronics termed
Cytomorphic Electronics, electronics inspired by cell biology. These
chapters discuss applications of bio-inspired systems to engineering and
medicine, deep connections between chemistry and electronics, and provide a
unifying viewpoint of ultra-low-power design in biology and in electronics;
Part VII. Energy Sources: A chapter on batteries and electrochemistry
discusses how batteries work from a unique circuit viewpoint. The last
chapter discusses energy harvesting in biomedical systems at portable
scales (vibration and body heat) and at larger scales (low-power cars and
solar cells). Principles of low-power design are shown to extend from small
scales in electronics to larger scales and to non-electrical systems. This
book reveals the deep connections between energy use and energy generation,
vital for sustainable energy systems of the future.
