Biomedical signals and sensors 2

En savoir plus sur le livre

This book set bridges physiologic mechanisms and diagnostic human engineering. The first volume focuses on the interface between physiologic mechanisms and resulting biosignals, while the second volume explores the relationship between biosignals and biomedical sensors. The first volume describes how physiologic mechanisms determine biosignals, from basic cellular interactions to advanced coordination levels. In contrast, the second volume examines the genesis of acoustic and optic biosignals and the associated sensing technologies from a strategic perspective. A key innovation is the discussion of heterogeneous biosignals within a unified framework, encompassing both the biosignal formation from physiological sources to their propagation in the body, and the sensing path from transmission in sensors to conversion into electric signals. Some biosignals emerge from vital bodily functions, while others represent these functions to convey physiological data. The interaction of sound and light with biological tissues, resulting in acoustic and optic biosignals, is highly instructive. This exploration reveals insights into the physics of sound and light, as well as biology and physiology. The interdisciplinary nature of biosignals and biomedical sensors presents challenges, yet offers rewarding insights when approached strategically, as outlined in this volume. The book aims to address intriguing “Aha!” questions.
