Biomedical engineering (or bioengineering; not to be confused with biotechnology) is a branch of engineering that applies principles of physics, chemistry, biology, materials science, and other related disciplines to the design of systems and solutions for biomedical sciences.

The purpose of this integration is mainly aimed at the technological, industrial, scientific, clinical, hospital fields.

Historically it was born on the one hand thanks to the applications of various disciplines mechanics, electronics, chemistry, etc. developed autonomously within its own field starting from the developments of biomechanics, biochemistry, biomaterials, electrophysiology, neurophysiology, cognitive sciences, biosystems; on the other hand, from the cybernetic synthesis approach tending to focus on the biomedical system in question (an organ, a cell, an organic function, a biochemical process, a health facility, an operating room, etc.) solving its problems with the various knowledge of engineering.

Today the identity of biomedical engineering is consolidated as an autonomous discipline and at the same time transversal to other traditional engineering disciplines, being the application of these to biology and medicine. The various branches derive from this physiognomy:

  • The industrial bioengineering group comprises biomechanical engineering, biochemical engineering, and biomaterials engineering.
  • The information bioengineering group comprises electronic bioengineering, bioinformatics engineering, bionics, biomedical modeling, biomedical signal engineering, and biomedical and health systems engineering.

Difference between bioengineering and biomedical engineering

Engineering is the application of physical and mathematical sciences in order to create, design, and innovate structures, processes, and tools to make human life more comfortable and simple.

In recent years, the study of engineering has been further divided into separate disciplines according to the principle and material that is used to create a new invention. For this reason, biological engineering and biomedical engineering have emerged as new frontiers in the field of engineering.

Biological and biomedical engineering are both highly advanced sciences that have helped shape the modern world we live in. These fields have contributed to progress in the biological sciences and medical sciences.


Bioengineering is also known as biological engineering, biological systems engineering, and biotechnological engineering.

It is a discipline that studies the application of the principles and methods of mathematics, chemistry, physics, and computer science in order to analyze and design new processes or tools to fill gaps in the life sciences. For some experts in the field, bioengineering represents a broad specialty that covers biomedical engineering, medical engineering, and biochemical engineering.

Compared to biomedical engineers, bioengineers focus on creating new products such as pharmaceuticals, food supplements, preservatives, bio-nanotechnology, and biomass-based energy using basic concepts and processes in biological science.

Fundamental engineering principles such as thermodynamics, kinetics, separation and purification methods, polymer science, fluid mechanics, heat and mass transfer, and surface phenomena are used in innovation and in the design of new products. Bioengineering is further divided into the following specialties: food and biological process engineering, agricultural engineering, and natural resource engineering.

Biomedical Engineering

Biomedical Engineering uses the fundamental principles of the biological sciences, medical sciences, and engineering to improve human health.

It integrates engineering sciences with biomedical sciences and clinical practice. This discipline deals with the understanding and acquisition of new knowledge of living systems through analytical and experimental methodologies based on engineering principles. In addition, biomedical engineering focuses on the production of new systems, tools, and processes that improve the discipline of medicine and biology for better delivery of quality health care.

Branches of biomedical engineering

Biomedical engineering has several subdisciplines: systems biology and bioinformatics, physiological modeling, biomechanics, biomedical instrumentation, and biomedical sensors, biomedical imaging, biomolecular engineering, and biotechnology and artificial organs.

Systems biology and bioinformatics focus on modeling new cell phones, networks, DNA sequence analysis, and microarray technology.

Physiological modeling studies the physiology of excitable cells, the dynamics of the microcirculation, models of cell mechanics, and pharmacokinetic models of drugs. Biomechanics involves the innovation of joint and limb prostheses and the study of gait analysis.

Biomedical instrumentation and biomedical sensors study clinical monitors such as an echocardiogram, oxygen sensor, blood glucose meters, and cardiac pacemakers.

Biomedical imaging deals with radiographic imaging, optical imaging, computed tomography, and magnetic resonance imaging. Biomolecular engineering and biotechnology studies drug delivery systems, protein engineering, vaccines, tissues, engineering, and separation methods. Artificial organs study the design of biomaterials that can be used to create new organs or systems that mimic their function.

Difference bioengineering and biomedical engineering

Bioengineering and biomedical engineering are two major advances in science and technology.

Both of these sciences use basic engineering principles, which involve the use of systematic analysis and processes in the design of new materials that will help solve basic problems in the life sciences. However, these disciplines differ in focus.

Bioengineering is a broader field of study, which includes biomedical engineering in its realm. Bioengineering focuses on the application of engineering to biological, food, agricultural and environmental processes.

On the other hand, biomedical engineering focuses on the application of engineering to the biological and medical sciences to improve healthcare delivery systems. Compared to bioengineering, biomedical engineering has more complex subdivisions, which focus on the field of study of particulate matter in order to improve human health.
