The mechanical properties of the skin are important to ensure human safety in human-robot collaborative environment. Therefore, in this study, a tensile test was performed at a strain rate of 0.001/s to measure the quasi-static properties of the pig skin. Tensile stress relaxation experiment was also performed to measure dynamic (viscoelastic) properties of pig skin. When both of the determined material properties were used together for finite element analysis to predict the Force-time curve obtained in drop impact test, reasonable consistency was observed, which indicates the validity of the determined mechanical properties of the pig skin.
