Traditional strategies for coloration based on selectively absorbing materials like pigment and dye cannot meet the high-resolution display and imaging requirements. With the recent advances in nanotechnology and nano- optics, tailoring the structure parameters of artificially fabricated nanostructures (such as metamaterials and metasurfaces), renders significant benefits for achieving tunable colorations. Compared with other color genera-tion mechanisms, those structural colors are bright and immune to bleach.Recently, an actively tunable structural color rendering with tensile substrate has been reported in Advanced Optical Materials. In this work, the tensile substrate (e.g., polydimethylsiloxane, PDMS) has been introduced into the conventional plasmonic structures to demonstrate the dynamic tunable structural colors. The proposed structure fabricated via interference on PDMS has been experimentally realized, and it shows that resonance-in-duced colors in the Al-PDMS composite structures can be dynamically tuned from green to fuchsia by stretching the tensile substrate in the macroscopic measurements. Moreover, the further theoretical analysis of the physical mechanism in the proposed structure has been investi-gated. This devised method has potential applications in anticounterfeiting, biometric sensors and mechanics measurement.
