Biomedical Engineering


Biomedical engineers have, in just a few years, revolutionised the field of medicine with their inventions. Some examples are the artificial heart and other organs, prosthetics (artificial limbs), the use of laser in surgery, cryosurgery and ultrasonics and the use of computers and thermography in diagnosis.

Biomedical engineers use the principles of engineering and life sciences and conduct research on the biological aspects of human and animal life.

Specialisations

Biomedical research encompasses broad areas of study - mechanical, chemical, electrical engineering, anatomy, physiology and the knowledge of computers to create mathematical models that simulate physiological systems.

Biomedical engineering coordinates the work of life scientists, medical professionals and chemical scientists. Some established areas of specialisation are:

Bioinstrumentation

This is the application of principles of electronics and measurement for the development of devices for use in diagnosis and treatment of desease. Computers are very vital in this speciality.

Biomechanics

Application of mechanics to medical problems. Artificial kidneys, hearts and hips are some examples of this.

Biomaterials

Selecting living tissue and materials for implant purposes in the human body.

Systems Physiology

Biochemistry of metabolism and limb movement control is a crucial area of study.

Rehabilitation Engineering

This deals with improving capabilities and the quality of life of individuals with physical impairments.

Employment

Biomedical engineers are usually researchers and work in laboratories in study, design or teaching.
