Currently and increasingly, biosensors are present in our daily lives, even if tendentiously and imperceptibly. As such and given their importance, the scientific community is clearly interested in making progress in this research field. This study is part of the study of biosensors using pre-gelled electrodes and was focused on the analysis of the ability to extract information on the quality of training, emotional state of the military, load and cognitive awareness, as well as the physical condition of the soldier of the future, through their biological signals, extracted and processed by BITalino’s biosensors and microcontroller, automatically. This analysis materialized experimentally through the classification of two emotional states, calm and stress, for which up to 98.18% accuracy was achieved.
