TLDR
In vivo frictional properties of human skin and five materials, namely aluminium, nylon, silicone, cotton sock, Pelite, were investigated and the palm of the hand has the highest coefficient of friction.Abstract:
In vivo frictional properties of human skin and five materials, namely aluminium, nylon, silicone, cotton sock, Pelite, were investigated. Normal and untreated skin over six anatomic regions of ten normal subjects were measured under a controlled environment. The average coefficient of friction for all measurements is 0.46±0.15 (p < 0.05). Among all measured sites, the palm of the hand has the highest coefficient of friction (0.62±0.22). For all the materials tested, silicone has the highest coefficient of friction (0.61±0.21), while nylon has the lowest friction (0.37±0.09).read more

Three-dimensional finite element analysis of the foot during standing—a material sensitivity study
TL;DR: The effects of soft tissue stiffening on the stress distribution of the plantar surface and bony structures during balanced standing were investigated and showed that a five-fold increase in soft tissue stiffness led to about 35% and 33% increase in the peak plantar pressure at the forefoot and rearfoot regions, respectively.

TL;DR: The material parameters obtained in this study will help to develop biofidelic human brain finite element models, which can subsequently be used to predict brain injuries under impact conditions.

Tribology of Skin: Review and Analysis of Experimental Results for the Friction Coefficient of Human Skin
TL;DR: In this paper, the authors discuss the current knowledge on the tribology of human skin and present an analysis of the available experimental results for skin friction coefficients, showing 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 contacting materials.

State-of-the-art research in lower-limb prosthetic biomechanics-socket interface: a review.
TL;DR: In this article, the authors review the recent research literature on socket biomechanics, including socket pressure measurement, friction-related phenomena and associated properties, computational modeling, and limb tissue responses to external mechanical loads and other physical conditions at the interface.

TL;DR: Increasing skin hydration seems to cause gender-specific changes in the mechanical properties and/or surface topography of human skin, leading to skin softening and increased real contact area and adhesion.

Shear vs pressure as causative factors in skin blood flow occlusion
TL;DR: Application of this device to the thenar eminence of 4 healthy subjects showed that externally applied pressure was approximately twice as effective as shear in reducing pulsatile arteriolar blood flow.

TL;DR: It has been established that the behaviour of skin is not portrayed by the simple laws of friction, but by a more complex relationship of the type F =μWn, probably because skin is subject to viscoelastic rather than purely plastic deformation.

Frictional properties of human skin: relation to age, sex and anatomical region, stratum corneum hydration and transepidermal water loss.
TL;DR: The findings suggest that frictional properties of skin are dependent on more than water content or non‐apparent sweating and the role of sebum secretion is suggested as one possible factor.

Tactile roughness of grooved surfaces: A model and the effect of friction

TL;DR: In this paper, a model based on the static deformation of the skin touching the stimulus tile is developed, and 11 parameters of the deformation are individually compared with the experimental data.

Grasp stability during manipulative actions.
TL;DR: The control of adequate contact forces between the skin and an object (grasp stability) is examined for two classes of prehensile actions that employ a precision grip: lifting objects that are "passive" and preventing "active" objects from moving.
