Stimuli-responsive solution amount variation is reversible and it has shown promising programs, which may be prospect of contraction or expansion fabrication, generating shrinking or swelling volume of the initial. In this study, a thermo/photo dual-crosslinking hydrogel is ready with methacrylated hydroxylbutyl chitosan (MHBC) and gelatin methacrylate (GelMA). The M/G hydrogel goes through sol-gel phase transition under room temperature and shrinking deformation upon elevating temperature. Besides
