Researchers from North Carolina State University and the Leibniz Institute for New Materials in Germany have demonstrated that stretching shape-memory polymers embedded with clusters of gold nanoparticles alters their plasmon coupling, giving rise to desirable optical properties. One potential application for the material is a sensor that relies on optical properties to track an object or environment's thermal history. An important application of thermal-history sensors is assuring the quality or safety of shipping or storing materials that are sensitive to significant changes in heat.
