IPA: /ˌbaɪəʊməˈtɪəriəl/
KK: /ˈbaɪoʊməˌtɪrəl/
A material that is safe to use in the body, often made from natural or synthetic substances, used in medical devices or to replace body tissues.
Doctors use biomaterials to create artificial organs and prosthetic limbs.
Biomaterial is formed from "bio-" (from Greek "bios", meaning life) and "material" (from Latin "materialis", meaning pertaining to matter or substance). The word refers to substances that are derived from living organisms or are compatible with living systems.
Think of 'bio' meaning 'life' and 'material' referring to 'substance' — so biomaterial is a substance related to life.
