Study Notes
Passive Smart Materials
- Passive smart materials do not have the ability to transduce or actuate energy on their own.
- They respond to environmental changes without generating an action or output.
Active Smart Materials (Type I)
- Active smart materials possess the ability to change their geometric and material properties when an external stimulus is applied.
- An example includes materials that change color in response to exposure to sunlight, indicating their reactive nature.
Energy Transformation in Smart Materials
- Certain smart materials can convert energy from one form to another.
- These materials can, for instance, convert electricity into light, demonstrating their ability to act as transducers.
External Stimuli
- Smart materials can respond to various external stimuli, leading to significant changes in their properties.
- Common stimuli include temperature changes, light exposure, electric fields, and magnetic fields.
- The controlled response to these stimuli distinguishes smart materials from traditional materials.
