BIOMEDICAL SIGNALS AND SENSORS II - EUGENIJUS K...

The book set develops a bridge between physiologic mechanisms and diagnostic human engineering.
While the first volume is focused on the interface between physiologic mechanisms and the
resultant biosignals  this second volume is devoted to the interface between biosignals and
biomedical sensors. That is  in the first volume  the physiologic mechanisms determining
biosignals are described from the basic cellular level up to their advanced mutual coordination
level. This second volume  considers the genesis of acoustic and optic biosignals and the
associated sensing technology from a strategic point of view. As a novelty  this book discusses
heterogeneous biosignals within a common frame. This frame comprises both the biosignal
formation path from the biosignal source at the physiological level to biosignal propagation in
the body  and the biosignal sensing path from the biosignal transmission in the sensor applied
on the body up to its conversion to a  usually electric  signal. Some biosignals arise in the
course of the body's vital functions while others map these functions that convey physiological
data to an observer. It is highly instructive how sound and light beams interact with
biological tissues  yielding acoustic and optic biosignals  respectively. Discussed phenomena
teach a lot about the physics of sound and physics of light (as engineering sciences)  and  on
the other hand  biology and physiology (as live sciences). The highly interdisciplinary nature
of biosignals and biomedical sensors is obviously a challenge. However  it is a rewarding
challenge after it has been coped with in a strategic way  as offered here. The book is
intended to have the presence to answer intriguing Aha! questions.
