Here, a free‐standing, skin‐like and highly stretchable metasurface with the mechanical modulation of the terahertz transmission is illustrated. In article number 2002484, Yuhang Li, Taisong Pan, and co‐workers fabricate the stretchable metasurface by merely constructing an Al/PI mesh film consisting of serpentine‐like unit cells, only with a total thickness of 7 μm. The metasurface shows the band‐stop frequency selective effect because of the periodic Al/PI mesh composition. With the novel mechanical design, the metasurface can be stretched, bent and twisted, which provides the possibility to modulate terahertz transmission properties by the mechanical deformation.

可拉伸的超颖表面：皮肤超薄可拉伸超颖表面的机械太赫兹调制（Small 37/2020）

在此，展示了具有太赫兹传输机械调制的独立式，皮肤状和高度可拉伸的超颖表面。在编号2002484中，李宇航，潘太松和他的同事们仅通过构建由蛇纹状晶胞组成的Al / PI网膜（总厚度仅为7μm）来制造可拉伸的超颖表面。由于周期性的Al / PI网格组成，超颖表面显示了带阻频率选择效应。利用新颖的机械设计，可以拉伸，弯曲和扭曲超颖表面，这提供了通过机械变形调节太赫兹传输特性的可能性。
