Smart material

From Wikipedia, the free encyclopedia

Smart materials, also called intelligent or responsive materials,[1][page needed] are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, moisture, electric or magnetic fields, light, temperature, pH, or chemical compounds. Smart materials are the basis of many applications, including sensors and actuators, or artificial muscles, particularly as electroactive polymers (EAPs).[2][page needed][3][page needed][4][page needed][5][page needed][6][page needed][7][page needed]

Terms used to describe smart materials include shape memory material (SMM) and shape memory technology (SMT).[8]
