DHS Wants to Turn Cell Phones Into Chemical Sensors – Security Management

The Department of Homeland Security’s (DHS) research and development arm wants to turn the smartphone in your pocket into the high-tech equivalent of a canary in a coalmine—all for about a dollar a phone.

On Friday, the Department of Homeland Security’s Science & Technology Directorate (S&T) announced it has begun to fund its Cell-All program, which has been in the research phase since 2007, reports Information Week. The program would embed a chemical sensor worth about a dollar into every cell phone, which would detect deadly chemicals without harming the smart phone’s battery life.
