BioSense Watch is the world’s first health band with on-board air quality monitoring, specifically the AirSenseM1 air quality module. This module incorporates three distinct sensors to enable real-time measurements of indoor air quality (IAQ), outdoor air quality (OAQ), general air quality (GAQI) (and, for good measure, ambient temperature and humidity).
AirSenseM1 uses MEMS (microelectromechanical systems) and an MOX chemiresistor, drawing ultra-low power from the BioSense itself, plus algorithms
and AI to detect as accurately as possible indoor and outdoor gas compounds. Specifically, AirSenseM1 includes:
- A gas sensor module to detect ozone and nitrogen dioxide
- A gas sensor module for TVOC and indoor air quality
- A high performance relative humidity and temperature sensor
When not worn, the device can also act as a stable air quality monitor, such as when placed on a kitchen counter.
Because the BioSense Watch acts as a wearable air quality monitor, it is mostly used in fast-changing, fluctuating, and complicated circumstances. The wearer is likely to frequently move between indoor and outdoor environments, and the defining line between “indoor” and “outdoor” is hard to distinguish. For example, if someone is sitting inside next to a widely opened window.
To address these “middle areas” and provide a helpful, all-around measurement for users, Vyvo Technology developed a General Air Quality Index (GAQI). This unique metric reports an overall air quality based on all the results from the sensors, considering all measured gasses, IAQ, AQI, temperature, humidity, etc.
Similar to how our wearables already measure wellness data every 10 minutes, BioSense Watch automatically captures AQI data and estimates a general AQI every 10 minutes. The GAQI is the best possible representation of the air quality immediately around the device user at any given moment. Equipped with this information, the device user can make informed decisions about whether to exercise, and which is the best location, indoors or out.
