“…In most of these reviewed studies, the skin is stationary and a probe of various materials slides or rotates over the skin. During the last couple of years, a number of studies have emerged, where friction is measured while moving a finger over an object or a surface, which is more pertinent for psychophysical studies [5][6][7][8][9][10][11][12][13][14][15]. In order to more accurately mimic sensory perception, Gee et al [5] developed a friction device with the aim of measuring friction between a finger and different materials.…”

“…This skin model was then used to study lubrication effects of different artificial skin surface lipid films by Gerhart et al [9], with a steel ball as a tribo partner. Furthermore, a couple of studies have combined finger friction measurements and sensory evaluation [6,7,12,13]. Childs and Henson [6] measured friction between a finger and screen-printed surfaces with different patterns.…”

“…Both the sliding friction coefficient and the roughness (peak separation) could partially be related to the perceived feelings. Moreover, friction measurements between an index finger and different car interior materials and aluminium samples with different roughness have been performed by Liu et al [7] in order to investigate touch-feel perception. In summary, both measured surface roughness and friction could be correlated with the ''rough-smooth'' and ''grippy-slippery'' perceptions.…”

A macroscopic finger friction device consisting of a piezoelectric force sensor was evaluated on 21 printing papers of different paper grades and grammage. Friction between a human finger and the 21 papers was measured and showed that measurements with the device can be used to discriminate a set of similar surfaces in terms of finger friction. When comparing the friction coefficients, the papers group according to paper grade and the emerging trend is that the rougher papers have a lower friction coefficient than smoother papers. This is interpreted in terms of a larger contact area in the latter case. Furthermore, a decrease in friction coefficient is noted for all papers on repeated stroking (15 cycles back and forth with the finger). Complementary experiments indicate that both mechanical and chemical modifications of the surface are responsible for this decrease: (1) X-ray photoelectron spectroscopy measurements show that lipid material is transferred from the finger to the paper surface, (2) repeated finger friction measurements on the same paper sample reveal that only partial recovery of the frictional behaviour occurs and (3) profilometry measurements before and after stroking indicate small topographical changes associated with repeated frictional contacts.

“…Moreover, friction is mostly measured by probes, passive touch and/or synthetic skin (e.g. Derler, Schrade, & Gerhardt, 2007;Derler, Gerhardt, Lenz, Bertaux & Hadad, 2009;Liu, Yue, Cai, Chetwynd & Smith, 2008). Roughness is a well researched property in haptic texture perception for macro as well as micro textures (Hollins & Bensmaïa, 2007).…”

The present thesis is based on three studies that research different aspects of fine texture perception. The goal is to better understand the mechanisms involved in haptic perception of textures below 200 µm, also known as microtextures. Study I was conducted to establish a friction measurement model and relating the friction measurements to perceived coarseness of fine textures. A set of printing papers was used as stimulus material. In Study II an expanded set, including the set of Study I, was used as stimuli in a multidimensional scaling (MDS) experiment of haptic fine texture perception. Through scaling of perceptual attributes and similarities, a three dimensional space was found to best describe the data and the dimensions were interpreted as rough-smooth, thick-thin and distinct-indistinct. In Study III a series of model surfaces were manufactured with a systematically varied sinusoidal pattern, spanning from 300 nm to 80 µm. As in Study II, a similarity experiment was conducted and a two dimensional space was chosen, the dimensions of which were explained well through friction and the wavelength. Together these three studies form a better picture of fine texture perception. The dimensionality found with paper stimuli was very similar to the corresponding spaces for marcrotextures of everyday materials, even though a different perceptual system is used for fine texture perception. Regardless if the information is coded through the spatial or the vibratory sense, the perception does not seem to differ in dimensionality. Further, the largest among the microtextures seem to have been perceived as carrying spatial information. On the systematically varied, rigid, textures, the MDS space did not come out in a similar fashion to those of everyday materials but instead similar to the physical properties that characterizes the change in the textures. It was further found that the participants in Study III successfully discriminated textures with an amplitude of 13 nm from the unwrinkled surfaces. From these studies the main conclusions are (a) haptically measured friction and surface roughness are important contributors to fine texture perception, (b) even at microscales, spatial information is retrieved haptically, probably through vibrations, and (c) persons can haptically discriminate textures at a nanoscale.

Cosmetic powder suspensions in compliant, fingerprintlike contacts

Cosmetic powders are regularly employed in skin creams and cosmetic formulations to improve performance and enhance skin feel. A previous study investigated the effect of particle concentration and size on the lubricating properties of powder suspensions in smooth, compliant contacts [Timm et al., Tribol. Int. (2011)]. In this paper the tribological properties of cosmetic powder suspensions are investigated in compliant contacts having model fingerprintlike surface topography. Friction coefficients were measured for a series of powder suspensions with varying particle size and concentration in a polydimethylsiloxane (PDMS)/PDMS contact. A commercial tribometer (MTM, PCS Instruments) was employed to measure friction as a function of rubbing time (20 min), under pure sliding (50 mm/s) and low load (0.5 N) conditions. Compared to results using smooth surfaces, it was clear that surface topography has a pronounced affect on the timedependent tribological behavior of the cosmetic powder suspensions studied. A two-stage friction coefficient versus time curve was observed. By varying the particle size and concentration it was shown that the duration and magnitude of each stage can be controlled.
