What are the differences between smart materials, composite materials and nano materials?
Smart materials are at least dual function, composites are materials composed of dissimilar phases or components (sometimes they’re called hybrid materials now), and Nano materials have been engineered on the Nano-scale Smart materials have multiple functions, which generally include sensor/actuator ability in addition to having form, or being able to support at least some structural weight. The classic example is Nitinol, which is a Nikcle-Titanium allow. After mechanical deformation (for example, bending), it can be heated up and will return to the pre-deformed structural shape. Lead-Zirconate-Titanate (PZT) is a ceramic, which responds to mechanical deformation by generating an electrical potential. In the reverse, an applied electrical potential leads to a geometric expansion of the material (actuator function). Composites are materials that are combinations of at least two different materials, which allow the engineering of desired properties (like tailoring mechanic...
