In the sliding contact between the fingerpad and a rough surface when touching a product's
surface, friction plays a role in the perception of roughness, slipperiness and warmth. For …

The coefficient of friction of most solid objects is independent of the applied normal force
because of surface roughness. This behaviour is observed for a finger pad except at long …

Most everyday surfaces are randomly rough and self-similar on sufficiently small scales. We
investigated the tactile perception of randomly rough surfaces using 3D-printed samples …

The topic of this paper concerns the relation between friction perception and finger friction
behaviour. Two experiments were processed for some 20 individuals. The aim of the first …

This study investigates how the fingerpad hydrolipid film, shape, roughness and rigidity
influence the friction when it rubs surfaces situated in the slippery psychophysical …

Human skin is characterised by a complex and highly variable friction behaviour. Although
the variation of friction coefficients measured for skin depends on numerous parameters …

The triangular ridged surface can improve the grip reliability of products, but the sharp edge
of triangular ridge induces sharp and uncomfortable feeling. To study the effect of edge …

This study formulates a finite element algorithm for frictional contact of solid materials,
accommodating finite deformation and sliding. The algorithm uses a penalty method …

Background Humans can recognize the physical properties of objects by touching them,
even when vision is unavailable. Tactile perception is important for humans in interacting …

A new methodology to determine experimentally the Young's modulus of the human fingers
has been developed by the authors. The methodology consist in the experimentally variation …
