smart materials are materials that responds to a stimulus like heat or light and then return to their original state hen the stimulus is removed,

Thermo - heat

Hydro - liquid

Chromic - colour

photo - light

bio - biological

react - change

thermochromic materials change colour when they reach a certain temperature

photocromic materials change when they are exposed to sunlight

hydrocromic materials change when they are exposed to a liquid

bio smart materials have a biological function such as killing bacteria

SMA - smart memory alloys

nitonal - smart wire which changes its length hen heated used in dental braces

flexium - used for stents which are put in arteries to keep blood flowing and needs to be bio safe
