The standard thicknesses for skin and fat are 1mm and 5mm, respectively.
Standard adult skin exhibits a mean force of approximately 2N in our penetration test, this selection is an appropriate mimic for most skin on the human body (face, forearm, groin, etc). Skins exhibiting greater penetration values are appropriate for thicker or more callused areas (abdomen, lower back, etc.) of the body. Typical human pain threshold occurs in the 2-4N range.
Basic model construction employs our patented SynTissue brand synthetic human tissues. These materials are experimentally designed on the basis of physical tests performed on actual living tissue. Each tissue is validated (tensile modulus, abrasion resistance, penetration force, coefficient of friction, thermal conductivity, dielectric constant, etc.) under the same physical conditions as the live tissue it is designed to simulate. The resulting synthetic tissue responds to stimulus much like the real living tissue.
