With the commercialization of electrical products, systems and processes in the last century came the branch of electrical engineering, involving the design and application of electronics and electricity to modern society. Electrical engineering has many subdisciplines, and engineers often specialize in a combination of them.

Another especially impressive field of study is that of biomedical engineering, which concerns the application of the problem-solving principles of engineering to the biology and medical sciences. Particularly in the last century, astonishing advancements in science and technology have come out of this field. Scientists and engineers are constantly improving health care treatments with new breakthroughs in modern medicine in regards to therapy, diagnosis and monitoring techniques. There are many subdisciplines and topics within biomedical engineering and they all require years of study to fully understand; some of these fields include bioinformatics, biomechanics, biomaterials, tissue engineering, genetic engineering, neural engineering and pharmaceutical engineering. Biomedical engineering is one of the highest regarded professions in the world.
