What is Biomedical Engineering?

Biomedical Engineering (BME) is an interdisciplinary field that applies engineering principles and design concepts to medicine and biology for healthcare purposes. This field seeks to close the gap between engineering and medicine, combining the design and problem-solving skills of engineering with medical and biological sciences. BME focuses on advancing the health care treatment, including diagnosis, monitoring, and therapy.

Brief History and Pioneers

The history of biomedical engineering is a tapestry of innovation and discovery. One of the earliest instances of biomedical engineering is the development of prosthetic limbs in ancient civilizations. However, the field as we know it began to take shape in the 20th century.

Key pioneers include:

• Willem Kolff, inventor of the dialysis machine.
• Robert Jarvik, known for developing the Jarvik-7 artificial heart.
• Wilson Greatbatch, the inventor of the implantable pacemaker.

These innovators laid the groundwork for countless life-saving technologies.
