Biomechanical Engineering is the application of mechanical principles on living organisms. Research and analysis of the mechanics of living organisms and the application of engineering principles to and from biological systems are part of this field. Research and analysis can be performed on multiple levels, from the molecular to the tissue and organ level. The application of mechanical engineering knowledge, skills and principles involve the conception, design, development, analysis, and operation of biomechanical systems, including: artificial organs and prostheses bioinstrumentation and measurements bioheat transfer biomaterials biomechanics bioprocess engineering cellular mechanics design and control of biological systems and physiological systems.
