Technology is constantly changing and the researchers at the University of California, San Diego are trying to come up with a way to embed tiny sensors in your cell phone that can detect toxic chemicals in the air.  These silicon chips will be able to map the locations of these chemicals and alert emergency responders as well as you.   How’s that for an iPhone app?

According to Inhabitat.com, “Michael Sailor and his team at UC San Diego along with startup company Rhevision Technology, Inc. recently completed the tech’s first phase of development. Now, they’re working on a prototype that can work with a cell phone.”

How it works: A tiny, silicon chip is embedded into your cell phone.  The device will change color when it detects harmful chemicals, alerting you and emergency responders.

Currently the chip can only identify a handful of chemicals, but researchers are optimistic about its future.
