Bioelectromagnetism: Principles and Applications of Bioelectric and Biomagnetic Fields

Who this book is for

For biomedical engineering students who want to understand where an electrical measurement comes from before choosing sensors or processing its waveform. The book supplies a physical foundation that complements an instrumentation manual. Its attention to source models is especially useful when a recorded signal changes after electrode placement changes.

Prerequisites

Calculus, elementary electromagnetism and circuit concepts are useful. Review nerve and muscle physiology, and be prepared to connect a field model with a biological source.

What it covers

The treatment connects excitable tissue, volume conduction and measurement sensitivity. Biological and physical models explain how a signal reaches an electrode or magnetic sensor. Applications provide a way to test whether a proposed measurement is consistent with the source and geometry assumed.

How to use it

Draw the source, conducting region and recording arrangement for a simple example before doing algebra. Keep the physiological generator distinct from the measurement lead. Compare two electrode placements and predict the change in sensitivity. Follow the reciprocity argument carefully, then use it to relate a measurement problem to the corresponding stimulation model.

Edition and sources

The Oxford record identifies the 1995 print book, ISBN 9780195058239. The author-hosted web edition corrects errors and changes presentation, so print page numbers need care. The Tampere course cited here is historical Autumn 2009 adoption, not a current offering.
