TDA Wearable Smart Chemical Sensor: Small, Rugged Monitor Warns First Responders of Toxic Exposure

The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) is working with TDA Research, Inc. (TDA) through a Small Business Innovation Research (SBIR) award to develop a simple, inexpensive, wearable smart chemical sensor badge that has high sensitivity and selectivity to multiple toxic industrial chemicals at trace (low parts per million or ppm) concentrations, and that triggers alarms at permissible exposure limits, short-term exposure limits and time weighted average concentrations.
