Abstract
A method for fabricating an object to attenuate thermal sensation when handling the object at non-body temperature, and an object fabricated in accord with the method. There is first provided a substrate which has a first surface subject to handling. There is then formed upon the first surface of the substrate a coating. The coating has an optimal density, an optimal thermal conductivity and an optimal thickness such that when the substrate having the coating formed thereupon is equilibrated at a non-body temperature differing from a body temperature and the coating is subsequently contacted with a body at the body temperature during handling, the temperature of the surface of the coating at a contact point of the body with the coating changes precipitously to a temperature near the body temperature and subsequently returns towards the non-body temperature at a rate which permits handling of the coating at the location of the first surface of the substrate by the body with attenuated thermal sensation. The coating simultaneously also minimally attenuates a steady state thermal transfer with respect to the substrate in comparison with an otherwise equivalent substrate absent the coating.
