Metasurfaces have recently gained significant attention due to the strong capacity in light field manipulation. However, most traditional metasurfaces are fabricated on rigid substrates, which fix their functionality after fabrication and limit their applications in dynamic measurement fields. In this work, we designed and fabricated a silver metasurface embedded in a stretchable substrate for sensing applications. This metasurface can generate different point cloud patterns under varying stretch ratios when illuminated by a laser beam. By collecting and analyzing the patterns, we can precisely reconstruct the deformation of the metasurface. Furthermore, the sample exhibits excellent performance under incident light of various wavelengths. These results pave the way for developing microdevices with novel capabilities based on flexible metamaterials.

用于变形监测的可拉伸等离子体超表面


由于超构表面在光场操纵方面的强大能力，最近受到了极大的关注。然而，大多数传统的超表面是在刚性基板上制造的，这在制造后固定了它们的功能，并限制了它们在动态测量领域的应用。在这项工作中，我们设计和制造了一种嵌入可拉伸基材中的银超表面，用于传感应用。当被激光束照射时，这种超表面可以在不同的拉伸比下产生不同的点云图案。通过收集和分析这些图案，我们可以精确地重建超表面的变形。此外，该样品在各种波长的入射光下表现出优异的性能。这些结果为开发基于柔性超材料的具有新功能的微器件铺平了道路。
