Skin sensitivity to moderately warm or cold temperatures can affect comfort, usability and injury potential. To quantify the thermal characteristics of materials that come in contact with the skin, surface temperature may be measured. Common applications include seating, hand tools, mattresses and other product that a user may come in contact with.  The thermal performance may allow product comparisons or be assessed relative to desirable thermal limits.
