GE: Wearable Airborne Chemical Sensor Bags $2mil Award from NIH.

National Institutes of Health (NIH) – awarded GE’s Global Research Lab for the extended development of a wearable airborne chemical sensor. An application derived from the chemical sensing characteristics found on butterfly wings.

According to Radislav Potyrailo, such application is beneficial in early detection for ultra-trace concentrations of airborne chemical threats. He says, existing sensors fall short in an array of practical situations. He says the GE team is focusing on detection in complex environments where existing sensors have too many false positive responses. Examples include air at a workplace, in cities, on a battlefield, in packaged food containers and exhaled air from medical patients. “For these and many other demanding applications, existing sensors suffer from responses to not only chemicals of interest in the air but also to numerous interferences that are present at much higher concentrations than the chemical of interest,” he says.

The sensor will use Radio Frequency Identification (RFID) technology and combines it with gas detection capabilities. Just imagine having this with you anywhere, you can use it to analyze your breath and diagnose presence of certain diseases.
