Abstract

<p>In order to determine drastic temperature dependence of collagen and skin specific heat ranging 25-75℃, we performed a non-equilibrium heat conduction experiment and its calculation. The specific heat was varied to minimize the error between the measured temperature and calculated temperature. The equation which is able to calculate composite material specific heat was applied to determine collagen specific heat by above mentioned method. Determined specific heat of collagen was described as follows: 3.06± 0.28 J/g·K (T<50℃), 7.61± 0.74 J/g·K (50≦T<55℃) and 5.61 ± 0.74 J/g·K(55℃≦T). The specific heat of porcine skin was determined by the same method. Determined specific heat of the skin was described as follows: 3.06± 0.36 J/g·K (T<55℃), 6.26± 0.22 J/g·K (55≦T<60℃), 3.26 ± 0.22 J/g·K (60℃≦T)</p>
