This work describes an isoprene sensor/breathalyzer concept for the detection of sleep disorders. Breath isoprene is proposed here as a biomarker signaling wakefulness according to reports in the medical literature. Hexagonal tungsten trioxide was used as the sensing element and it was able to detect and discriminate among various isoprene concentrations in the range of 300 ppb to 1 ppm and above-the range of interest for the targeted application. The fast response, high sensitivity, and noninvasive, non-intrusive nature of the isoprene detector suggests that it can potentially be used as a diagnostic tool for sleep apnea.
