Bioelectronics is emerging as a new area of research where electronics can selectively detect, record, and monitor physiological signals. This is a rapidly expanding area of medical research, that relies heavily on multidisciplinary technology development and cutting-edge research in chemical, biological, engineering, and physical science. This book provides extensive information on the (i) fundamental concepts of bioelectronics, (ii) materials for the developments of bioelectronics such as implantable electronics, self-powered devices, bioelectronic sensors, flexible bioelectronics, etc, and (iii) an overview of the trends and gathering of the latest bioelectronic progress. This book will broaden our knowledge about newer technologies and processes used in bioelectronics.
