We studied stable nitrate ion-selective field-effect transistors (ISFETs) to detect human salivary nitrate using direct potentiometry. We investigated several biocompatible polymer based nitrate ISFETs as polymer matrix material. The prepared NO 3 --ISFETs showed almost the theoretical Nernst response over 10 -5.5 M to 10 -0.5 M with a response time of less than a few seconds except for Tecoflex ® . As we applied whole human saliva using direct potentiometry, we obtained good relationship with conventional ion chromatography in case of KP-13 based ISFETs. We will also introduce several acute stress subjects for healthy volunteers using wearable heart rate monitor and salivary nitrate by prototype of nitrate FET checkers.

“…So far we have used salivary NO 3 -concentration index, mainly in handling-a-ship simulator experiments to evaluate mental workload quantitatively [1] [2]. And then we confirm the numerical values given by salivary NO 3 -concentration index corresponds to the subject's mental workload fluctuation, compared with various physiological indices, which we have also tried to use to correspond numerical values by these indices to navigators' mental workload fluctuation and as you thought these are sufficient to evaluate the mental workload of ship bridge teammates [3] [4].…”

We think that salivary NO 3 -concentration corresponds to mental workload. To confirm that, so far we have a lot of experiments for navigators in handling-a-ship simulator, which can be arranged an experiment's surroundings. Through this experiment, we trust in the effectiveness of salivary NO 3 -concentration as a physiological index, because the salivary NO 3 -has a special characteristic to show quick response to mental workload on the spot and such trend as moving average. On the other hand, we confirm the effectiveness of a variety of physiological indices, heart rate variability (R-R interval), nasal temperature, and salivary amylase as well as salivary NO 3 -concentration, but these are not good at giving us a response of mental workload instantly because these physiological indices need to analyse numerical values from data. After all, to evaluate mental workload quantitatively by salivary NO 3 -concentration helps younger navigators to grasp the handling-a-ship skill of veteran navigators, in concrete terms younger navigators understand the risky handling-a-ship situations from mental workload veteran navigators feel. As mentioned earlier, salivary NO 3 -concentration is a good index to measure mental workload, however, actually measurement errors by this index occur in experiments. So in this paper, we confirm one of the errors, occurred by exercise, and can decrease the error.
