Skin
comfort, health and beauty are the concerns for people of all ages. The
interactions between products and human skin are within the field of
tribology, which has continuously attracted scientific studies over the
past years. Knowledge on the contact mechanics and friction behavior of
human skin is a prerequisite to improve and optimize surfaces and
materials which come in contact with the skin. It is possible to assess
friction and tactile properties in human and animal skin tests, while
instrumental tribological measurements are an efficient alternative,
providing objective and more reproducible results without inter- and
intra-subject variations. This is why the design of tribo-mechanical
skin equivalent is very significant, with which the mechanical contacts
between skin and external materials can be simulated close to practical
conditions.
Human
skin is a soft biomaterial with a complex layered anatomical structure,
being characterized by nonlinear viscoelastic material behavior and
showing a friction behavior that strongly depends on the contact
conditions. The objective is to develop an active layered
tribo-mechanical skin equivalent, which could representative real human
skin in terms of mechanical properties, friction behaviour, surface
topography, surface chemistry and humidity response. Both simulation and experimental work are expected.
