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.

Presents a strategic consideration of diverse biomedical signals with needed basics included Treats diverse biosignals and explains the needed basics for measurements Facilitates understanding and cooperation between engineers and live science Offers comprehensive but balanced entrance into the field of biomedical engineering Includes supplementary material: sn.pub/extras

Autorentext

Prof. Eugenijus Kaniusas graduated from the Faculty of Electrical Engineering and Information Technology of the Vienna University of Technology (VUT) in 1997. In 2001 he got the degree Dr. techn. He habilitated (venia docendi) in the field of bioelectrical engineering in 2006. Since 1997 he has been with the Institute of Fundamentals and Theory of Electrical Engineering, VUT, since 2007 as associate professor. He gives numerous mandatory lectures at VUT, concerning Biophysics, Biomedical Sensors and Signals, Biomedical Instrumentation. Since 2011 he is the chairman of the advisory board of study affairs of Biomedical Engineering at VUT. Currently he is the head of the research group Biomedical Sensing / Theranostics within the Institute of Electrodynamics, Microwave and Circuit Engineering, VUT. He has (co)authored more than 160 publications, two volumes books, 2 patents, and various invited book chapters. Since 1999 he has contributed to 19 national and international(including EU) projects, funded by public and industry, 10 of them being coordinated by him. He is engaged as reviewer for 20 international journals and for diverse research councils (e.g., ERC grants). He is organiser of special IEEE sessions and COST workshops and co-organiser of diverse international symposia.His research areas include diagnostic and therapeutic approaches and their closed-loop combination in portable Health Care Engineering. Electric, acoustic, optic, and magneto-elastic sensors for biomedical applications are developed, e.g., for sleep, anaesthesia and fitness monitoring as well as for apneas detection and heart rate variability monitoring. Electrical Impedance Tomography - enhanced by computer tomography - is developed for a novel individual setting of lung ventilators. Modelling of physiological signals and systems is performed for the voluntary breath holding (apnea diving) and the associated fitness assessment. Electric auricular vagus nerve stimulation isdeveloped to realise individualised Point-of-Care therapy in pain and arterial disease therapy, and in triggering healing of diabetic chronic wounds. Extensive expertise is available in adaptive, multiparametric, clinically-relevant processing of hybrid biomedical signals in the time, spectral, and space domains, and in wearable hardware/software concepts for diagnostic/therapeutic biomedical devices. He is Chief Technology Officer (CTO) in SzeleStim GmbH, a spin-off developing auricular vagus nerve stimulators for personalized treatment of pain and perfusion problems. Since 2018 he is the head of the Institute of Electrodynamics, Microwave and Circuit Engineering, VUT.
