|Abstract:||Realization of plasmonic nanostructures on flexible and stretchable substrates have attracted considerable attention because such integration provides novel functionalities for sensing applications. Here, we present a plasmonic tape by achieving metal nanostructures on the transparent tape with a simple transfer technique. Examples include the tapes with nanohole and nanoparticle arrays for refractive index and strain sensing, respectively. These continuing and discrete structures on tapes feature characteristic plasmonic resonances and excellent flexibility. The tape with the nanohole array shows higher sensitivity in the refractive index sensing than that on the rigid substrate. The nanoparticle array used in strain sensing discloses two plasmonic modes with different responses. This plasmonic tape offers a new flexible platform for plasmonic sensing and may open new application possibilities in scenarios inaccessible by conventional plasmonic sensors.|
