Semiconductor

A semiconductor is a solid material that has electrical conductivity in between that of a conductor and that of an insulator; it can vary over that wide range either permanently or dynamically. Semiconductors are tremendously important in technology. Semiconductor devices, electronic components made of semiconductor materials, are essential in modern electrical devices. Examples range from computers to cellular phones to digital audio players. Silicon is used to create most semiconductors commercially, but dozens of other materials are used as well.

Professional engineer

Engineers typically require a type of professional certification, such as satisfying certain education requirements and passing an examination to become a professional engineer. These certifications are usually nationally regulated and registered, but there are also cases of self-governing bodies, such as the Canadian Association of Professional Engineers. In many cases, carrying the title of "Professional Engineer" is legally protected.

As BME is an emerging field, professional certifications are not as standard and uniform as they are for other engineering fields. For example, the Fundamentals of Engineering exam in the U.S. does not include a biomedical engineering section, though it does cover biology. Biomedical engineers often simply possess a university degree as their qualification. However, some countries, such as Australia, do regulate biomedical engineers, however registration is typically only recommended and not required.
