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.
由于在光场操纵方面具有强大能力，超表面最近受到了广泛关注。然而，大多数传统超表面是在刚性基板上制造的，这使得它们在制造后功能固定，限制了其在动态测量领域的应用。在这项工作中，我们设计并制造了一种嵌入可拉伸基板的银超表面用于传感应用。当受到激光束照射时，这种超表面在不同拉伸比下会产生不同的点云图案。通过收集和分析这些图案，我们可以精确重建超表面的变形。此外，该样品在各种波长的入射光下都表现出优异的性能。这些结果为基于柔性超材料开发具有新颖功能的微器件铺平了道路。
