Breath Analysis

Breath analysis

Breath analysis is emerging as a powerful, non-invasive tool for personal health monitoring. The air we exhale offers immediate insight into our metabolic state, moving diagnostics beyond the clinic to accessible point-of-care and home settings.

Specific health issues leave unique traces in our breath. Gastrointestinal conditions like SIBO (small intestinal bacterial overgrowth), Lactose Intolerance, and Fructose Intolerance are reliably identified by measuring digestive gases like hydrogen and methane. Furthermore, persistent Halitosis is often linked to elevated levels of certain VOCs (Volatile Organic Compounds) and sulfur compounds. Accurately quantifying these biomarkers is critical for effective treatment and targeted dietary adjustment, empowering users to manage their health proactively.

ScioSense provides the high-precision sensor technology required for these advanced diagnostic applications. Our ENS16x gas sensors are central to the system, offering high-sensitivity detection of the key VOCs and reducing gases. Complementing this is the ENS21x, which delivers accurate temperature and humidity data crucial for correcting gas readings and ensuring sensor stability.

The system’s complete integration, often utilizing components like the AS6040 for reliable signal processing, facilitates the creation of compact, ultra-low-power diagnostic devices. This combination of high-precision sensing and low-power operation enables the next generation of portable breath analyzers. By monitoring breath for markers of SIBO and intolerances, ScioSense is facilitating personalized, proactive healthcare through reliable, accurate data.

Common sensor designs - gas meter. Having a low offset and offset stability in the range is even a bigger one. In addition, the amplitude of the receive signal will show strong variations in real applications.

ScioSense flow converters manage that challenges: An integrated charge pump allows to fire with up to 17V. Within the amplified received signal they measure multiple zero crossings. This improves the resolution of the total time-of-flight measurement.
