Sensitivity of the skin tissue on the activity of external heat sources

In the paper the analysis of transient temperature field in the domain of biological tissue subjected to an external heat source is presented. Because of the geometrical features of the skin the heat exchange in domain considered is assumed to be one-dimensional. The thermophysical parameters of successive skin layers (dermis, epidermis and sub-cutaneous region) are different, at the same time in sub-domains of dermis and sub-cutaneous region the internal heat sources resulting from blood perfusion are taken into account. The degree of the skin burn results from the value of the so-called Henriques integrals. The first and the second order sensitivity of these integrals with respect to the thermophysical parameters are analyzed. On the stage of numerical computations the boundary element method has been used. In the final part of the paper the results of computations are shown.
