Demonstration of extreme deformation attainable with AgNW embedded flexible transparent electrode.

(a) Relative change in the resistances of the ITO on PEN, AgNW on PEN and AgNW embedded NOA 63 as a function of bending radius. The inset shows a photograph of a folded AgNW embedded flexible transparent electrode with a bending radius of 150 μm set for the bending test. (b) Relative change in the resistances of the ITO on PEN, AgNW on PEN and AgNW embedded NOA 63 as a function of the number of bending cycles at the bending radius of 3.3 mm. The inset shows the resistance change with compressive and tensile stresses applied to the AgNW embedded NOA 63 electrode. (c) Photograph of AgNW embedded flexible transparent electrode that resembles a sheet of paper. The electrode is extremely deformable and can be repetitively folded and recover without deteriorating its conductivity. (d) Photograph of AgNW embedded flexible transparent electrode wrapped around a pencil with a radius of 3 mm. (e) Photographs of blue LED lamps mounted on AgNW embedded flexible transparent electrode transferred to various substrates, including crumpled paper, sharp wooded edge, human skin, stringed textile and rubber.
