This study is based on the effect of surface integration on the piezoelectric and mechanical properties of Zinc oxide  nanorods. To verify that surface integration effect exists for both soft and hard substrates, Graphene coated pet plastic substrates and silver coated glass substrates were used for the synthesis of ZnO nanorods. Few sample surfaces were integrated with ZnO nanoparticles before the growth while others were used without dispersion of ZnO nanoparticles. Acquired results revealed the divergence in growth densities of nanorods on both soft and hard substrates. A clear influence of surface integration was observed in the generated piezoelectric potential in both cases. Beside this mechanical stability of seed assisted ZnO nanorods was higher than the ZnO nanorods grown on nonintegrated substrate. This approach can help the research community in future for fabrication of high quality devices on soft and hard substrates as far as mechanical stability and piezoelectric properties are concerned.
