2. Use of Smart Materials.

Question

Accepted Answer

Smart materials are materials that can change their properties in response to external stimuli.

Smart materials have a wide range of applications in various fields such as aerospace, construction, and medicine.
Examples of smart materials include shape memory alloys, piezoelectric materials, and electrochromic materials.
Shape memory alloys can change their shape in response to temperature changes, while piezoelectric materials can generate electricity when subjected to mechanical stress.
Electrochromic materials can change their color in response to an electric current.
The use of smart materials can lead to the development of new technologies and products that are more efficient and effective.
In medicine, smart materials can be used for drug delivery, tissue engineering, and biosensors.
