Let $ (H, {\alpha}_{H}) $ be a Hom-Hopf algebra and $ (A, \alpha_{A}) $ be an $ (H, {\alpha}_{H}) $-Hom-bimodule algebra with the maps $ {\alpha}_A, {\alpha}_H $ bijective. Then in this paper, we first introduce the notion of Hom-twisted smash product $ (A{\star} H, {\alpha}_{A}{\star} {\alpha}_{H}) $ and then study the conditions for the Hom-twisted smash product and tensor coproduct to form a Hom-bialgebra and a Hom-Hopf algebra. Furthermore, we give a non-trival example of Hom-twisted smash product Hopf algebra and a characterization of left $ (A{\star} H, {\alpha}_{A}{\star} {\alpha}_{H}) $-Hom module.
