Stretchability of graphene-AgNW-embedded hybrid electrodes. (a) A photo of the hybrid electrode formed on a PDMS substrate. Scale bar is 1 cm. (b) Relative difference in the resistance as a function of tensile strain for hybrid structures embedded in PDMS. The AFM topographies of hybrid structures on PDMS (c) when releasing, (d) when re-stretching up to 33%, and (e) when re-stretching up to 66% after stretching up to 100%. (Here, AgNW networks were embedded in PDMS and a graphene layer was transferred onto the AgNW-embedded PDMS). Scale bars are 5 μm.
