Which technology is used in the development of smart clothing to monitor and regulate an athlete's body temperature?
-
Phase-change materials
-
Thermoelectric materials
-
Shape-memory materials
-
All of the above
A
Correct answer
Explanation
Smart clothing uses phase-change materials to monitor and regulate an athlete's body temperature. Phase-change materials absorb or release heat as they change from one phase to another, such as from solid to liquid or liquid to gas. This allows smart clothing to absorb heat from the athlete's body when they are overheating, and to release heat when they are too cold.
