“…33 Principal causes of PU are pressure, friction and shear, and the resulting sustained cell and tissue deformations, the e ects of which are exacerbated by moisture and temperature (Fig 1). 1,[34][35][36][37][38][39][40][41]…”

“…17,18 Friction of skin with contacting materials and surfaces is of great interest in the context of pressure injury prevention. 19 The coefficient of friction (COF) of skin when in contact with other materials varies with the anatomical site, age, ambient temperature, the level of tissue hydration, the level of wetness at the skin-material interface, and the amount of hair follicles and hair present on the skin. 20 For untreated, dry skin in contact with common medical textiles, the COF is approximately in the range of 0.4 to 0.6.…”

The objective of this article is to formulate a new bioengineering theoretical framework for modelling the biomechanical efficacy of cyanoacrylate skin protectants, with specific focus on the Marathon technology (Medline Industries, Inc., Northfield, Illinois) and its modes of action. This work details the bioengineering and mathematical formulations of the theory, which is based on the classic engineering theories of flexural stiffness of coated elements and deformation friction. Based on the relevant skin anatomy and physiology, this paper demonstrates: (a) the contribution of the polymerised cyanoacrylate coating to flexural skin stiffness, which facilitates protection from non‐axial (eg, compressive) localised mechanical forces; and (b) the contribution of the aforementioned coating to reduction in frictional forces and surface shear stresses applied by contacting objects such as medical devices. The present theoretical framework establishes that application of the cyanoacrylate coating provides considerable biomechanical protection to skin and subdermally, by shielding skin from both compressive and frictional (shearing) forces. Moreover, these analyses indicate that the prophylactic effects of the studied cyanoacrylate coating become particularly strong where the skin is thin or fragile (typically less than ~0.7 mm thick), which is characteristic to old age, post‐neural injuries, neuromuscular diseases, and in disuse‐induced tissue atrophy conditions.

“…Sustained pressure loads can result in skin and deep tissue damage (i.e. pressure ulcer), which is aggravated when augmented by interfacial shear [162][163][164] and an increased local temperature [32,165]. Pressure ulcers are related to compression-induced ischaemia (i.e.…”

“…These phenomena are not only central the study of mechanically-induced skin injuries, specifically skin tears, superficial pressure ulcers and friction blisters but are also of prime importance in incontinence. Incontinence associated with ageingand the search for effective solutions [174,175]is likely to become an increasingly important factor in the prevalence of skin injuries as it also compromise mechanobiological skin functions [165,176].…”

Biotribology of the ageing skin—Why we should care

et al. 2019

Ageing of populations has emerged as one of the most pressing societal, economic and healthcare challenges currently facing most nations across the globe. The ageing process itself results in degradation of physiological functions and biophysical properties of organs and tissues, and more particularly those of the skin. Moreover, in both developed and emerging economies, population ageing parallels concerning increases in lifestyleassociated conditions such as Type 2 diabetes, obesity and skin cancers. When considered together, these demographic trends call for even greater urgency to find clinical and engineering solutions for the numerous age-related deficits in skin function. From a tribological perspective, detrimental alterations of skin bioph ysical properties with age have fundamental consequences on how one interacts with the body's inner and outer environments. This stems from the fact that, besides being the largest organ of the human body, and also nearly covering its entirety, the skin is a multifunctional interface which mediates these interactions. The aim of this paper is to present a focused review to discuss some of the consequences of skin ageing from the viewpoint of biotribology, and their implications on health, well -being and human activities. Current and future research questions/challenges associated with biotribology of the ageing ski n are outlined. They provide the background and motivation for identifying future lines of research that could be taken up by the biotribology and biophysics communities.
