The dehydration of emergency disaster personnel can lead to severe physiological consequences being able to go until death. The follow-up of the sodium ions concentration in the sweat allows to evaluate this dehydration state in real time by a non invasive method and to react quickly in the case of such an dehydration event. This paper deals with the development of an Ionic Selective Electrode sensor and its transfer on fabrics. The performances were evaluated in terms of sensitivity, selectivity and reproducibility firstly in model solution and then in natural sweat. A portable electronic board connected to the sensing part is described too. This board drives the electrochemical and temperature sensors for analog acquisition and converts measurement data to digital value. Signal processing is implemented on the electronic board in order to correct raw data (gain, offset) and to convert them to ion concentrations.
