Scaffold metamaterial and its application as strain sensor

摘要: In this paper, strain sensors based on planar scaffold metamaterial design are demonstrated. The optical properties of such metamaterials studied, which proved to be highly dependent the deformation structure. Fabricating compliant polymeric substrate, geometric parameters could tuned with external and hence found control reflection resonance condition metamaterial. Such mechanical tunability provides opportunity realize efficient about 27 nm wavelength shift is observed by applying as much 37% tensile strain. Furthermore, distinct from most previous works, our structures “intaglio” design, manufactured directly one step fabrication using focused ion beam cutting, makes process simpler.
