It is important to clarify the relationship between the hemolysis amount and degree of surface roughness under blood shear fields. From our previous study, we have obtained that the increasing hemolysis was related to the increasing shear stress due to the surface roughness using a rotational shear stressor. However we have not yet measured the increasing shear stress with the stressor due to the torque sensor sensitivity. In this study, we used a double-cylinder type rheometer in order to detect a slight shear stress due to the surface roughness. As a result, hemolysis amount increased with the increase of shear rate and shearing time, we consider that this rheometer can measure the torque value due to the surface roughness, which cause hemolysis under shear fields.
