The friction behaviors of water and aqueous solutions of thickener were evaluated between a contact probe with a striped rough surface and a substrate. When the probe surface is flat, the contact states are the boundary lubrication and fluid film lubrication states for water and the thickener aqueous solutions, respectively. In contrast, for the contact probe with a striped rough surface, friction occurred under fluid lubrication state for both water and thickener solutions. These results indicate that the liquid in the depression on the striped rough surfaces changes the regime of friction.

We evaluated the frictional force between two finger models that mimic properties of fingertips. Friction dynamics were drastically changed with the presence of fingerprints and variations in sliding speed and vertical force. For example, a periodic variation of the frictional force was observed under slow sliding conditions between finger models with fingerprint-like rough surfaces.
