Security and Public Safety

Protecting the Public with Hazardous Gas Sensors

Industrial accidents can release a hazardous, airborne plume of chemicals and jeopardize the health of anyone in its path.  In the case of terrorist attacks, a plume can contain chemical or biological agents or, in the case of a dirty bomb, particulate matter contaminated with radiation. Early detection and real-time monitoring of hazardous plume location and intensity require a matrix of small, low-cost sensors deployed across the area of concern. Since the sensors will tend to be deployed at locations that are elevated and relatively inconvenient to service, they must be able to operate for long periods of time without the need for manual calibration or service.

The Molecular Property Spectrometer™ (MPS™) from NevadaNano is well-suited for ubiquitous deployment across a city or a large facility. A matrix of sensor modules thus deployed can sense and track hazardous plumes to guide evacuations enable optimum deployment of first responders, and provide data crucial for environmental mitigation.

Chemically Mapping Public Skies

In a separate implementation, NevadaNano, in collaboration with robot experts at the University of Utah, has worked to put the MPS™ aboard a highly maneuverable quadcopter, capable of autonomously avoiding obstacles while conducting real-time chemical mapping of airborne chemicals. Data are wirelessly relayed to a base station for visualization throughout a flight.
