Development of a calorimetric sensor for medical application. Part IV. Deconvolution of the calorimetric signal

Abstract

A calorimetric sensor has been developed for local and direct measurement of calorific dissipations in different parts of the human body. The constructed prototype has a detection surface of 36 cm(2). In this paper, a deconvolution method is proposed to reconstruct the dissipated power. The advantage of this method is that: to determine the dissipated power, it is not necessary to correct the baselines to calculate either the areas of the calorimetric signal or that of the dissipated power in the temperature control because the proposed method takes into account, apart from the calorimetric signal, the thermostat temperature and the ambient temperature.
