Rodríguez de Rivera* Departamento Física, Universidad de Las Palmas de Gran Canaria, 35017 Las Palmas de Gran Canaria, Spain A calorimetric sensor has been developed to measure surface heat dissipations in the human body.
An experimental prototype has been built in order to study its performance and a simple model that represents acceptably the experimental system has been proposed. Keywords: calorimetric model, heat-conduction calorimetry, medical calorimetry Introduction The instrumentation for the thermal measure has been developed mainly in the thermal analysis area.
In this area, countless devices have been constructed: one for every need and with the typical characteristics of the process that is intended to be studied [1, 2].
In calorimetry, it is necessary for the energetic process that is intended to be measured to be located in a controlled zone where the detector system output can be clearly related to the power and-or energy developed in this zone. The aim that has been proposed is to measure the heat dissipations developed in localized zones of the human body; in this case, the dissipation intended to be measured is not located in the inner part of the measurement instrument but in the outer part, that is the reason why the measurement process is out of the calorimetry standards.
However, it has been constructed an experimental prototype whose operating principle is based on the heat transference by conduction law.
Besides, as this instrument has a thermostat that remains at a constant temperature, isothermal calorimeters can be included within the heat conduction [3]. In this paper, it is shown an experimental prototype and a model that represents acceptably its performance. It is made a study of the influence of each one of the parameters of the model on the sensitivity of the device.
