Smartphones That Measure Body Fat, Radiation, Bad Breath?

Think your iPhone is intelligent? Just wait until you hear what the next generation of Japanese smartphones are capable of.

Next week at CEATEC Japan 2011, the country's largest mobile industry tradeshow, several new innovations will emerge that may change the way we interact with our phones forever.

Several companies are planning to unveil smartphones that feature different "jackets" of sensors that detect surprising environmental changes (and the software to process the data). With one, users will be able to employ their smartphones to measure the radiation levels of their surroundings -- a popular idea in Japan since this year's devastating earthquake and tsunami.

Another "jacket" would be able to detect whether a user has bad breath, while still another can calculate how much body fat or muscle he or she has.

One day, developers may even create a smartphone that can detect whether the user has alcohol on his breath or is being exposed to too much UV light.

Are these "jacketed" smartphones fact or fiction? We'll let you know next week as news from CEATEC comes our way.
