What is Biomedical Engineering

Biomedical engineering is a field that combines principles of engineering, biology, and medicine to develop innovative medical devices and technologies, improve healthcare, and solve medical problems. Biomedical engineers use their expertise in engineering and life sciences to design and develop medical equipment, prosthetics, diagnostic devices, and other healthcare products. They also work on developing new drugs and treatments, as well as researching and understanding biological systems to improve our understanding of human health and disease.

History

The field of biomedical engineering has its roots in the late 1800s, when engineers and physiologists began to collaborate on developing equipment to study the human body. In the early 1900s, the focus shifted to developing medical equipment, such as electrocardiographs and X-ray machines, that could aid in diagnosis and treatment.

During World War II, biomedical engineers worked on developing new medical technologies to treat wounded soldiers, such as the first artificial kidney, which was used to treat soldiers suffering from kidney failure. After the war, the field continued to grow, with new technologies and techniques being developed to treat a range of medical conditions.

In the 1960s and 1970s, advances in computer technology allowed for the development of more complex medical equipment, such as CT scanners and ultrasound machines. The field also began to focus more on developing prosthetic devices and other assistive technologies to improve the quality of life for people with disabilities.

Today, biomedical engineering is a rapidly growing field that continues to develop new technologies and techniques to improve healthcare and solve medical problems.

Becoming a Biomedical Engineer

To become a biomedical engineer, a strong educational background in engineering and life sciences is typically required. Most biomedical engineers hold at least a bachelor’s degree in biomedical engineering or a related field, such as electrical engineering, mechanical engineering, or chemical engineering.

In addition to a strong academic background, practical experience through internships, co-op programs, or research positions is highly valued in the field. Many universities offer undergraduate and graduate research opportunities for students interested in pursuing biomedical engineering.

Certification is not typically required for biomedical engineers, but some choose to become licensed professional engineers (PEs) to demonstrate their expertise and increase their job prospects.

Job opportunities for biomedical engineers are growing, with employment projected to grow much faster than the average for all occupations. Biomedical engineers can work in a variety of settings, including hospitals, research institutions, medical device companies, and government agencies.
