A breathalyzer in your smartphone case

Japanese mobile provider NTT Docomo offers some of the most interesting handset gear in the world, including a phone "jacket" that can tell you if you've had too much to drink.

BARCELONA, Spain--We're always intrigued by NTT Docomo's booth at trade shows, and this year's MWC is no different.

The company demonstrated a smartphone case with an embedded sensor for hygiene purposes. Similar to the ultra high-speed charging jacket, the device snaps onto the smartphone's chassis, much like a backup battery. However, there's a sensor, microchip, and NFC module embedded in this "jacket."

The most interesting capability of this sensor jacket has to be ranking your alcohol inebriation on a scale of one to five, one being the lowest. One thing it doesn't do is issue advice to prevent the user from drink driving, or at the very least, drunk texting.

The app is also able to measure how bad your breath smells, so you'll know when to cut down on those onion rings.
