Humans are electric beings. We are managed, monitored, and stimulated electrically. This textbook provides students and practitioners with a solid foundation and understanding of human electricity and the work currently being done to further develop electrical signals for medical purposes and related goals. The book introduces the fundamentals of how biological systems generate electrical signals, covering a wide range of biomedical engineering topics including bioelectricity, biomedical signals, neural engineering, and brain-computer interface. The book is presented in three sections: Part I explains how electrical signals and impulses manage the human body; Part II examines the kinds of electrical signals from the human body and how they are monitored, controlled, and used; Part III looks at clinical use of electrical stimulation toward the human body and how they are being developed for interventions in medicine. The book is also a valuable professional reference for practicing engineers and scientists. Explains humans as electric beings who are managed, monitored, and stimulated electrically; Deals with the electricity of major human organs; Covers a wide range of biomedical engineering topics
