Abstract

To research on the bio-tribological properties of intestinal mucous, the intestinal mucous is taken from a healthy pig which is used as the carrier. The experimental results show: (1) under the condition of intestinal mucous lubrication, friction coefficient decreases with moving speed increasing; as load increases, friction coefficient decreases. (2) Intestinal mucous has shear thinning property—viscosity decreases with strain rate increasing. When shear strain rate is less than 10/s, viscosity fluctuating amplitude becomes larger as shear time increases; when shear strain rate is more than 10/s, viscosity tends to be a constant as shear time increases. The results are of great significance to the structure design of miniature robotic endoscope.
