This paper presents a study to improve the calibration process of a calorimetric sensor for medical application. The sensor has been designed for determination of the heat loss, heat capacity and equivalent thermal resistance of the skin region on which the sensor is applied. Localized constants models have been found to be effective. For a good calibration of the sensor, suitable experiments have been designed, allowing us to determine the thermal quantities with acceptable accuracy. In addition, we propose a new method of operation, which does not require the initial placement of the sensor on the calibration base: the whole measurement is performed with the sensor applied on the skin. The operation and calculation methods were validated by simulations that aim to reproduce the human skin measurement. Finally, an application in the human body is presented, consisting of measuring the heat capacity and equivalent thermal resistance of the wrist.

本文提出了一项改进医疗应用量热传感器校准过程的研究。该传感器设计用于确定应用传感器的皮肤区域的热损失、热容量和等效热阻。已发现局部常数模型是有效的。为了对传感器进行良好的校准，我们设计了合适的实验，使我们能够以可接受的精度确定热量。此外，我们提出了一种新的操作方法，它不需要将传感器初始放置在校准底座上：整个测量都是在将传感器应用于皮肤的情况下进行的。操作和计算方法通过旨在再现人体皮肤测量的模拟进行验证。最后，
