The document discusses the past, present, and future of biomedical engineering. It describes how biomedical engineering has evolved from its origins in electronics to become a multidisciplinary field that develops new medical technologies. Examples are given of pioneering technologies from imaging to prosthetics. The future of the field is predicted to include more sophisticated implantable devices, tissue engineering, and neural interfaces. The document also discusses the International Federation for Medical and Biological Engineering, the largest organization in the field, which celebrated its 50th anniversary in 2009 and aims to advance biomedical engineering through international collaboration.
