Biomedical engineering is an interdisciplinary field that applies principles and technologies from the physical sciences—such as mechanical, electrical, and chemical engineering—to solve problems in medicine and biology. It focuses on the design, development, and application of medical devices, diagnostic equipment, and therapeutic systems. Core areas of study include biomechanics, the study of physical forces on biological systems; biomaterials, the creation of substances that interact with biological systems; and medical imaging, which utilizes physical principles to visualize internal structures. The field contributes significantly to areas like prosthetic limb development, drug delivery systems, and physiological monitoring, fundamentally aiming to improve human health outcomes through technological innovation.
