Biomedical Engineering
Is the engineering that is applicable to human health? It is concerned with what we put in our bodies and what we put on our bodies. The interest in this field spans a variety of problems.
Biomechanics
Biomechanics describes the disciplines which apply the science of mechanics to biological systems. These biological systems are not limited to the human body. Whereas mechanical systems involve the response to bodies discrete or continuous, rigid or deformable, solid, liquid or gaseous to the action of forces, biomechanics focus on kinesiology, the science of human motion and movement; the mechanical structural and geometric properties of the compartments of human body; sports mechanics, exercise and leisure activities, orthopedics, clinical, diagnostic and surgical procedures and the effects of vibration on the body.
Of major interest is the development of biocompatible implantable materials. Developments have been made in the area of organ replacement, advanced surgical procedures such as arthroscopy, microsurgery, breathing machines that can communicate with the wheelchairs.( this has aided rehabilitation in cases of spine and neck injuries). Biomechanics employs mathematical models and experimental tests to analyze biological systems and their responses to stress. Although much has been done biomechanics still seek to understand better the performance of the human body.
