This book deals with the principles and concepts of Biomedical Engineering in a simple and easy manner. The text is admirably suited to meet the needs of the students of mechanical engineering who opt for the elective Biomedical Engineering. However, coverage of bioinstrumentation, biomaterials and computing for biomedical engineering also meets the needs of electronics and instrumentation engineering students. Most of the questions have been taken from various university examination papers, specially from UPTU.
