Materials that can undergo an appreciable and controllable change in properties in response to a stimulus are known as active or smart materials. A number of materials exhibit this behavior, but only a few of them have been developed to a point where they have consistent properties and are available in commercial quantities. Widespread availability of quality materials has fueled a dramatic increase in the potential commercial use of these materials as is evidenced by the 600% increase in the number of patents involving active materials that have been issued over the past decade in the area of automotive applications alone. Recognizing the increasing need for familiarity with the characterization of active materials by practicing engineers, this series of articles provides an introduction to techniques for experimental characterization of commercially significant active materials. The materials include: thermally activated shape memory alloy wires; thermally activated shape memory polymers; magnetorheological fluids; dielectric elastomers; and piezoelectrics.
