“…Most participants have m stick and m slip ranging respectively from 0.5 to 3 and from 0.1 to 2.4, whereas these COFs rise up to 5.5 and 3.7 for a few subjects. Although being extremely high, these values have nevertheless been reported elsewhere [18].…”

“…But, for higher R a , the COF rises when roughness increases owing to the increase of skin deformation [17]. Moreover, for well-defined regular surfaces produced by laser texturing with a similar R a , the COF slightly depends on texture parameters such as asperity radius and spacing [18].…”

This study investigates how the fingerpad hydrolipid film, shape, roughness and rigidity influence the friction when it rubs surfaces situated in the slippery psychophysical dimension. The studied counterparts comprised two 'real' ( physical) surfaces and two 'virtual' surfaces. The latter were simulated with a tactile stimulator named STIMTAC. Thirteen women and 13 men rubbed their right forefingers against the different surfaces as their arms were displaced by a DC motor providing constant velocity and sliding distance. Tangential and normal forces were measured with a specific tribometer. The fingerpad hydrolipid film was characterized by Fourier transform infrared spectroscopy. The shape and roughness of fingers were extrapolated from replicas. Indentation measurements were carried out to determine fingerpad effective elastic modulus. A clear difference was observed between women and men in terms of friction behaviour. The concept of tactile frictional contrast (TFC) which was introduced quantifies an individual's propensity to distinguish two surfaces frictionally. The lipids/ water ratio and water amount on the finger skin significantly influenced the TFC. A correlation was observed between the TFC and fingerpad roughness, i.e. the height of the fingerpad ridges. This is essentially owing to gender differences. A significant difference between men's and women's finger topography was also noted, because our results suggested that men have rougher fingers than women. The friction measurements did not correlate with the fingerpad curvature nor with the epidermal ridges' spatial period.

“…Furthermore, the application of LST has been expanded to bio-tribology in the recent years. In the Netherlands, samples with well-defined surface topography were used to unlock the "feel" of surfaces by an experimental study on the relation between surface texture and tactile friction [68]. The microgeometries of the metal samples were fabricated by picosecond laser pulses, also used as injection molds for thermoplastic polyurethane (TPU) samples in experimental work (refer to Fig.…”

This review gives a concise introduction to the state-of-art techniques used for surface texturing, e.g., wet etching, plasma etching, laser surface texturing (LST), 3D printing, etc. In order to fabricate deterministic textures with the desired geometric structures and scales, the innovative texturing technologies are developed and extended. Such texturing technology is an emerging frontier with revolutionary impact in industrial and scientific fields. With the help of the latest fabrication technologies, surface textures are scaling down and more complex deterministic patterns may be fabricated with desired functions, e.g., lotus effect (hydrophobic), gecko feet (adhesive), haptic tactile, etc. The objective of this review is to explore the surface texturing technology and its contributions to the applications.

“…Groove patterns, for example, as the most common geometric structure, were studied and found to have the ability of reducing the tactile friction during fingertip exploration [31]. Recent studies are focused on the influential factors like the material properties, skin condition, and contact parameters of the counter-body and the skin [27,35]. The real contact area plays a pivotal role in skin friction.…”

Surface texture is important for contact mechanical and tribological phenomena such as the contact area and friction. In this research, three different types of geometrical microstructures were designed and fabricated by pulsed laser surface texturing as semi-symmetric (grooved channel), asymmetric fractal (Hilbert curve), and symmetric patterns (grid). A conventionally finished surface as a reference sample from the same stainless steel sheet material was compared. From the experimental approach, a multiaxis force/torque transducer was used to investigate the functionality of surface texture based on measuring the tactile friction in three different sliding directions: perpendicular, parallel, and 45°to the textures. According to the dynamic friction measurements, the grid texture was indeed orientation independent. The other samples showed orientation-dependent frictional behavior, especially the grooved channel texture and reference sample. Furthermore, an analytical approach was applied to estimate the values of the friction coefficient by the pressure distribution method. From both the experimental and analytical approaches, the grid pattern was validated to be the optimal texture design in the concern of friction reduction and orientation-independent behavior.
