“…For the non-treated Neolite footwear pad, the COF increased with the particle size of steel grit, especially under the water and glycerol contaminated condition. The results proved that the anti-slip effect will be improved by increasing the particle size of steel grit and was similar with the results of, Chang et al [15], Sariisik et al [16] and Sariisik [17]. However, the results were different from the study of The Institute for safety & Health [18].…”

Anti-slip strip was one of the most popular slip-resistant products indoor and outdoor, especially on the ramp. By using anti-slip strip the roughness of floor can be increased, the COF will be increased and the risk of slips and falls will be reduced at the same time. This study wanted to find out the effects of slip-resistance under different particle sizes of steel grit, different floor contamination conditions and different inclined angles while using the emery anti-slip strip. The results demonstrated that the particle size of steel grit used on the emery anti-slip strip has significant influence on the COF. When footwear had no groove under the shoe sole or the groove had been abraded badly, the particle size had to be big enough to perform the function of the anti-slip especially under the floor contamination of glycerol and water. Therefore, the study suggested that the particle size of steel grit used on the emery anti-slip strip should be larger than 500μm to provide fine anti-slip effects.

“…For comparable contact pressures, the mean friction coefficients of fingers and the edge of the hand against wet smooth glass were 0.14 ± 0.03 [82]. Other studies investigating the friction of foot skin on wet floor surfaces also found critical friction coefficients between 0.1 and 0.2 for a range of smooth materials such as glazed ceramics, steel and polished marbles [56,113,114].…”

Tribology of Skin: Review and Analysis of Experimental Results for the Friction Coefficient of Human Skin

In this review, we discuss the current knowledge on the tribology of human skin and present an analysis of the available experimental results for skin friction coefficients. Starting with an overview on the factors influencing the friction behaviour of skin, we discuss the up-to-date existing experimental data and compare the results for different anatomical skin areas and friction measurement techniques. For this purpose, we also estimated and analysed skin contact pressures applied during the various friction measurements. The detailed analyses show that substantial variations are a characteristic feature of friction coefficients measured for skin and that differences in skin hydration are the main cause thereof, followed by the influences of surface and material properties of the contacting materials. When the friction coefficients of skin are plotted as a function of the contact pressure, the majority of the literature data scatter over a wide range that can be explained by the adhesion friction model. The case of dry skin is reflected by relatively low and pressureindependent friction coefficients (greater than 0.2 and typically around 0.5), comparable to the dry friction of solids with rough surfaces. In contrast, the case of moist or wet skin is characterised by significantly higher (typically [1) friction coefficients that increase strongly with decreasing contact pressure and are essentially determined by the mechanical shear properties of wet skin. In several studies, effects of skin deformation mechanisms contributing to the total friction are evident from friction coefficients increasing with contact pressure. However, the corresponding friction coefficients still lie within the range delimited by the adhesion friction model. Further research effort towards the analysis of the microscopic contact area and mechanical properties of the upper skin layers is needed to improve our so far limited understanding of the complex tribological behaviour of human skin.
