same surroundings and lead similar lifestyles, there are noticeable differences in their psychological makeup [7]. Tribological assessments of skin are conducted for fasci­nating information about how the skin reacts to different materials, how the proper­ties of skin are changed depending on factors like age and health, and by a range of ailments and chemical treatments [24]. The upsurge of cosmetic industry and the effects of skin care products were the primary objectives of tribological studies on skin, or they addressed dermatological issues such skin condition, ageing, skin inju­ries, wound healing, and prosthesis [10]. The usage of face masks has expanded as a result of the recent Covid-19 pandemics; however, these masks can induce skin lesions because they apply constant pressure, tension, and friction to the skin (20). The initial tactile encounter with a product, whether it’s an automotive interior or a portable music player, greatly inuences its perceived worth. Only a small number of skin tribology works concentrated on theoretical inquiries, with the majority using experimental methods [21]. Engineering a product’s tactile nature for better sensory perception has the ability to transform product design. Products may cause friction­induced damage to the skin, including blistering. Correlations between human sen­sory outcomes (e.g. softness, smoothness, leather-like feel) and quantitative physical qualities (e.g. friction coefcient, elastic modulus) have proved challenging to estab­lish [8]. It should be noted that tribological measurements offer a minimally invasive approach for quantitatively evaluating the moisture content and general health of skin constitutes one of the advantages they offer [24]. Studies examined the role of skin friction, particularly that of the nger pad, in relation to the sense of touch clas­sied within an additional eld [10]. There appears to be a fresh trend in materials development that incorporates human considerations like skin compatibility, tactile perception, touch characteristics, and ergonomics more and more [10]. To improve and optimise surfaces and materials that come into touch with the skin, knowledge of the contact mechanics and friction behaviour of human skin is a must [10]. Current tribological investigations on materials contacting the skin include textiles, accept­able surfaces for consumer products, medicinal and sports applications [10]. It is well known that materials and objects’ tactile qualities depend heavily on their fric­tion and surface features. Human subject testing can be used to evaluate friction and tactile characteristics; however, instrumental tribological measures are a useful sub­stitute that yield objective, more repeatable results (with no inter- and intra-subject variances) [10]. Due to this, attempts have been made to use mechanical skin models in conjunction with tribological testing, which simulates real-world mechanical con­tacts between the skin and exterior materials [10]. A study discussed the tribological properties of newer types of ceramics, glasses, polymers, and coatings while analys­ing the demand for advances in tribology from the material point of view [5]. To create articial skin and improve prosthetic implants, it is necessary to research the tribological characteristics of human skin [28]. The ndings suggest favourable tri­bological behaviour can be achieved via material modications (i.e. microstructural changes), hybrid constructions, and specic (solid) lubrication and coatings. These ndings highlight “advanced material” tremendous potential for tribological applica­tions [5]. The review focuses on the tribology of human skin, analysing experimental results for skin friction coefcients.
