Well, your cell phone might soon become its own canary as well. The U.S. Department of Homeland Security — specifically, its Science and Technology Directorate division — wants to help create 40 prototypes, by the end of this year, of cell phones that can detect toxic chemicals in the air just as easily as they can receive a call or send a text message.
The initiative, dubbed Cell-All, wouldn’t allow participants to operate some kind of Star Trek-style tricorder scan for poisonous gas (unfortunately). According to Physorg.com, all manufacturers would need to do is embed a small chip into the phones — costing a little less than a dollar — that would detect toxic chemicals in the air while a user goes about his or her normal activities. Depending on the nature of the gas detected, the phone could alert a user with a vibration or a noise to indicate that unsafe activities are amiss and, “getting the heck out” should commence.
For more potent chemical activities — like a toxic gas attack — the phone would anonymously send a message back to a centralized service to report its findings. But here’s the fun part. Rather than raise the alarm and force authorities to take action, which would prove costly should numerous phones glitch and fire up an occasional false alarm, said reporting service would take into account the reports of phones across a larger geographic area.
For example, suppose a poisonous gas was released at a shopping mall. Instead of relying on one phone’s report of a problem — which may or may not be a true indication of what’s really going on — the service would look for correlated reports across a number of devices in a particular location. According to Physorg.com, the entire process of detection, reporting, and notification could take place in less than 60 seconds. And since all users equipped with chemical-sensing phones would be serving as their own walking sensors of-sorts, emergency responders could use the more comprehensive analysis to pinpoint exactly where they need to concentrate their efforts.
