Artificial Skin Model simulating dry and moist in vivo human skin friction and deformation behaviour

In vivo friction and indentation deformation experiments were carried out using the human volar forearm of a healthy 29 year old Caucasian woman and compared with various synthetic materials in order to select materials and develop a new moisture-sensitive Artificial Skin Model (ASM). Analogous to human skin the final ASM comprised two different layers: a relatively stiff hydrophilic moisture absorbing, top layer representing the epidermis and a very soft under-layer representing the dermis and hypodermis. The friction and deformation behaviour of the new ASM were comparable to human skin when tested under dry and moist skin conditions. This development has potential for use as a test-bed in the development of devices that interact with the skin in a mechanical way. (C) 2016 Elsevier Ltd. All rights reserved.
