An example of a badge-type sensor would be a vapor-monitor badge (e.g., for organic vapors and other volatile substances). Some of these badges are "dosimeter" badges that measure dose of exposure over time; many of these badge types would need to be sent away for analysis (which would be impractical for a first-responder scenario.) Watch-type sensors were referenced more broadly as a wearable-type sensor, but these sensor types have been studied or commercialized for physiological monitoring and not hazardous materials detection.

We don't want to limit the technology to specific compounds/chemicals. However, hazardous gases, flammable liquids and solids, toxic chemicals, and explosives are common in emergency response incidents.

The sensor should not impede the emergency responder's mobility when responding to hazmat emergencies.

The sensor should not be destroyed or need significant maintenance/parts replacement after a single emergency response event. Considerations include but are not limited to: regular wear and tear, heat exposure, cold exposure, shock/impact, exposure to hazardous materials. The sensor should be able to withstand everyday use.

Ideally, the sensor would be embedded within the PPE so emergency responders would not have to remove the sensor or have the risk of the sensor to accidentally being removed during emergencies.

Battery documentation is not always readily available on-site and documentation may not accurately reflect the battery's properties (e.g., advertised capacity is inaccurate.) Voltage is not the best measure for state of charge, as the relationship between voltage and SoC is not linear.

The minimum operational time would be 30 minutes. Ideally, the device should be operable throughout emergency response events.

We are looking for sensors that can target a range/multitude of hazardous materials, which could include but are not limited to radiological/nuclear sensors.
The ideal use cases would be for emergency response to hazardous materials incidents, which can include but are not limited to: train derailments resulting in hazardous materials spills or fire, hazardous materials spills from transport vehicles, hazardous gas release/dispersion, and explosions.
