Interprétation tribologique de la perception tactile de surfaces texturées
International audience; Ces dernières années, l’industrie a porté un intérêt grandissant à la qualité sensorielle de leurs produits, et notamment à la sensation tactile qu’ils procurent. Selon Hollins et al, l’ensemble des surfaces matérielles peuvent être définies selon quatre dimensions psycho-perceptives tactiles : « glissant/collant », « lisse/rugueux », « chaud/froid » et « dur/mou » [1]. La texturation de surface est un moyen de parvenir à la réalisation d’une variété de surfaces appartenant, du point de vue de la perception tactile, aux deux premières dimensions susnommées. Néanmoins, les liens entre les paramètres topographiques des textures et la sensation ressentie lors du toucher…
Tribological interactions related to the tactile perception of deterministic micro-textured surfaces
International audience; In recent years, industrials paid a growing attention in qualifying and even predicting the tactile perception of their products. Surface texturing offers a reliable route to control surfaces tactile perception but relation between textured surface topography and tactile perception remains still unclear. Moreover, while tactile perception originates from the transmission of friction forces and friction induced vibrations to mechanoreceptors located in the dermis, a better understanding of the fingerpad/surface tribologic interaction is needed. Recently, many efforts were made to correlate friction forces to textures parameters on the one hand [1], and textures parame…
Tactile perception of textured surfaces: a tribological interpretation
International audience; In recent years, industrials paid a growing attention in qualifying and even predicting the tactile perception of their products. Surface texturing is an exciting option to control surfaces tactile perception. Nevertheless, relations between textured surface parameters and tactile perception remains unclear. Hence, a better understanding of the finger / surface contact is necessary. This study aims at investigating the relationships between the tactile perception of textured surfaces and the tribological behaviour of the finger / surface contact. Ten textured surfaces characterized by equally distributed 100 μm tall cylindrical dots were studied. Dots diameter D vari…
