1. A multi-waveband-tunable multi-scale meta-material, comprising:
a stretchable layer, a non-stretchable support layer, a metal layer, and a nanoparticle layer sequentially stacked from bottom to top, wherein the stretchable layer is a polydimethylsiloxane (PDMS) layer; the non-stretchable support layer is a polyimide (PI) layer; the metal layer is a gold layer; and the nanoparticle layer is modified with a hydrophobic group.
