Biomedical engineers come from one of the traditional engineering disciplines, such as electrical or mechanical engineering.

Biomedical engineers are exposed to many fields of study in engineering, medicine and biology. Due to this broad experience biomedical engineers find employment in:

New fields of Biomedical Engineering

Medical instrumentation is the application of electronics and measurement techniques to develop devices used in diagnosis and treatment of disease.

Computers are an important and increasingly essential part of medical instrumentationExamples of medical instrumentation include: heart monitors, microelectrodes, defibrillators, glucose monitoring machines etc.

Biomaterials are defined as the materials used for medical implantation includes both living tissue and artificial materials.

Examples of biomaterials include:Heart replacement valvesArtificial lungs Artificial kidneysDental adhesivesBone cementReplacement bones/jointsHeart prostheticsEtc.

Biomaterials must have following properties:NontoxicNon-carcinogenicChemically inert (not reacting violently with the

body's chemical composition)StableMechanically strong enough to withstand the

repeated forces of a lifetime of use.

‘Human Physiology’ is the study of the body and its functions in each of the different systems in any living body

Modeling is used in the analysis of experimental data and in formulating mathematical descriptions of physiological events

Examples: Biochemistry of metabolism and the control of limb movements

Collection and analysis of data (signal) from patients

The manipulation and dissection of the data or

signal provides the physician and experimenter the vital information on the condition of the patient.

Biomedical Engineers apply signal-processing methods to the design of medical devices that monitor and diagnose certain conditions in the human body.

Examples: Heart arrhythmia detection software and brain activity

Medical Imaging combines knowledge of a unique physical phenomenon (sound, radiation, magnetism etc.) with high-speed electronic data processing, analysis and display to generate an image.

Examples: Magnetic Resonance Imaging (MRI)Ultrasound and computed tomography (CT).

Biomechanics applies both fluid mechanics and transport phenomena to biological and medical issues.

It includes the study of motion, material deformation, flow within the body, as well as devices, and transport phenomena in the body, such as transport of chemical constituents across biological and synthetic media and membranes.

Efforts in biomechanics have developed the artificial heart, replacement heart valves and the hip replacement.

Rehabilitation engineering is the systematic application of engineering sciences to design, develop, adapt, test, evaluate, apply, and distribute technological solutions to problems confronted by individuals with disabilities.

Functional areas of rehabilitation engineering may include mobility, communications, hearing, vision, and cognition, and activities associated with employment, independent living, education, and integration into the community.
