Definitions for "Smart materials"
those materials that respond to differences in conditions, egs. temperature, pH or light. They are smart because they sense conditions in their environment and change accordingly; they are responsive and appear to think; they may also appear to have a ‘memory' and revert back to their original state
Here, materials and products capable of relatively complex behavior due to the incorporation of nanocomputers and nanomachines. Also used for products having some ability to respond to the environment. [NTN] If you combined microscopic motors, gears, levers, bearing, plates, sensors, power and communication cables, etc., with powerful microscopic computers, you have the makings of a new class of materials: "smart materials." Programmable smart materials could shape-shift into just about any desired object. A house made of smart materials would be quite useful and interesting. Imagine a wall changing color at your command, or making a window where their was none before. [Bill Spence
Materials able to detect a change in the environment and react to it.
