SafeScent

ACTIONABLE, REAL-TIME INDOOR AIR QUALITY INSPECTION AND MONITORING FOR SAFER AND MORE PRODUCTIVE INDOOR ENVIRONMENTS

World Health Organization (WHO) data shows that air pollution kills an estimated seven million people worldwide every year. The short term effects of exposure to pollutants can cause problems such as sneezing, coughing, eye irritation, headaches, and dizziness; while long term exposure is linked to higher rates of cancer, heart disease, stroke, and respiratory diseases.

Chemical indoor air pollutants and sources can include fuel-burning appliances, tobacco smoke, household cleaning chemicals, building materials, furnishings, fireplaces, pet litter, spoiled food, volatile organic compounds (VOCs) from mold and mildew, and volatiles from airborne pathogens.

SafeScent is the world’s first intelligent air quality monitoring and inspection eNose to deliver real-time alerts on the specifics of the contaminant and therefore the source, for healthier and safer environments. Based on NASA patents, SafeScent is AI-driven, portable, cloud-connected, real-time, software upgradeable, and low-cost. It provides real-time indoor air quality actionable data for safer and more productive environments.

PRODUCT OVERVIEW

Stratuscent’s SafeScent eNose solution captures simple and complex everyday scents, as well as the tiniest scent nuances that are undetectable by the human nose, and it digitizes them into scentprints.

This is how it works
Powered by its proprietary sensors and cloud-based AI, SafeScent can detect harmful vapors that are often odorless to humans and even complex malodors in the environment. Whether it is your kitchen, room, or car cabin, SafeScent can alert the user when their environment has any harmful volatiles or undesirable malodors for which it has been trained.

Through its ability to cross-learn from other devices in use, SafeScent is always getting smarter so that it can detect an increasing number of volatiles in various environments.

SAFER, HEALTHIER AND MORE PRODUCTIVE LIVING AND WORKING ENVIRONMENTS

AI-Enabled Electronic Nose (eNose)
SafeScent’s AI-enabled eNose can be installed either as a standalone unit or be integrated into existing airflow systems, HVACs, exhausts or return ducts. The standalone SafeScent unit includes Stratuscent’s proprietary sensor, pump assembly, and the electrical chipset. Depending on the application, the SafeScent unit can leverage existing airflow or be equipped with a quiet built-in pump.

At the core of the SafeScent eNose is its 32-sensing-element chemiresistive array sensitive to various functional groups of Volatile Organic Compounds (VoCs) that are important to our safety and comfort. As the air flows over this array, the impedance of the sensing elements changes to create a scentprint unique to the type and concentration of the volatile(s). This scentprint is continuously digitized and relayed to the Stratuscent cloud for interpretation through a secure and encrypted communication protocol.

Thus, SafeScent can predict the quality of the air based on its holistic scentprint.

Bio-Inspired and Cloud-Enabled Artificial Intelligence (AI)
Much like how our olfactory system works, the signal from the sensor (the “nose”) is sent to the AI-enabled cloud (the “brain”) for processing. Using proprietary machine learning techniques, the AI engine is able to not only detect the differences between different scentprints that correspond to various volatiles, different concentrations, and their mixtures, but is also able to detect changes in the scentprints as the air quality changes in various humidity and temperature conditions and in the presence of complex background scents.

In a true bio-mimicking fashion, just like how we don’t switch our noses between smelling a rose or perfume, SafeScent doesn’t need to be changed for different target volatiles. In fact, it can be trained with an unlimited number of new volatiles and scents. Leveraging the capabilities of the Stratuscent cloud, the same eNose unit can be remotely software-upgraded with improved capabilities, unfamiliar background, or additional volatiles. Each SafeScent eNose learns from all the other eNoses.

Intelligent Client UIs
SafeScent comes with intelligent web-based Application Programming Interfaces (APIs) that can be seamlessly integrated with new or existing User Interfaces (UIs). These APIs can be used to get real-time air quality information and send alerts when the air quality degrades to undesirable or unhealthy levels.
